WARNING: This post contains spoilers for Deathstroke Inc. #5, on sale now from DC Comics.
Ever since Crisis on Infinite Earths in 1985, reboots have been a major part of how DC handles its comics. For nearly forty years now, their solution to their most complicated continuity problems was to rewrite reality so that those problems no longer existed. Although this has created high-stakes epics with major moments for some of its biggest characters, it has sometimes grated on fans. For example, the New 52 publishing initiative left some readers disillusioned with the constant reboots, especially when it removed some of their favorite characters.
With the launch of "Infinite Frontier", however, DC has embraced their entire 80-year history and it looks like they aren't going back. Many of their recent comics since have had an emphasis on preventing the next big Crisis and the fear characters have surrounding them. Recently, that was seen in Deathstroke Inc. #5 (by Joshua Williamson, Paolo Pantalena, Hi-Fi, and Steve Wands).
It was revealed that T.R.U.S.T. was actually a new Secret Society of Supervillains all along. However, rather than contributing to a new Crisis as they did in Final Crisis (by Grant Morrison and others), they want to prevent it. Being made up of obscure villains, they have the most to lose if reality is reset. They might be totally changed or no longer exist at all. This was also a major factor for another villain team, Injustice Incarnate, in the Infinite Frontier limited series (by Joshua Williamson and Xermanico). Heroes and villains alike were assembled by Darkseid to take down Justice League Incarnate because of their fear for the multiverse, which they saw as the cause of each devastating Crisis.
Some of these characters had lost much in the various Crisis events that came before (like those from the Pre-Crisis Earth-2), whilst others simply feared that it would be their turn next time around. However, this doe not necessarily mean that DC's ditching them altogether.
What suggests that this is their new approach to their comics and characters is what happened both during and after Death Metal. At the end of that event series, when Wonder Woman confronted the Hands, an ancient and mysterious cosmic race responsible for the creation of various multiverses throughout the Omniverse, they expressed that they themselves disliked the cycle of endless reboots that the DC Multiverse had gone through. They were going to wipe out the DC Multiverse because of this until Diana proved that it was worth saving. For DC to go back to the cycle of reboots again after that story would feel like a major step back.
Since then, many aspects of characters' histories have come back into canon and been used to great effect. For instance, Stephanie Brown and Cassandra Cain being Batgirls again or Wally West returning as the Flash and getting his old life back, kids and all. These have been great stories that have delighted readers.
Beyond good stories for restored characters, what else is there? There are teams like Justice League Incarnate and the Totality. Both of these teams are dedicated to defending against multiversal threats, like a Crisis. The Totality itself is dedicated solely to preventing more reality-altering reboots and has yet to be fully explored. Therefore, it would seem out of place to have them fail before they even got started.
Infinite Frontier made it clear that there will be another Crisis event soon. However, that doesn't necessarily mean a reboot is coming. Before Crisis on Infinite Earths, a "Crisis" was a multiversal threat but it didn't mean a reboot until 1985. Perhaps now that DC has restored its history, it's reclaiming the original meaning of the word Crisis too. Now that there's a greater focus on the multiverse and an Omniverse to explore, this would be the perfect direction for DC to go in and abandon reboots for good.
