I honestly don't expect anything nearly as impressive as what we currently have in the Doom community. While there's still plenty of folks making PWADs and IWADs that are vanilla Doom compatible, the ZDoom team has brought the technology of Doom so far that it's some mishmash hybrid of capability of Quake 1-2, and folks not only make amazing free mods for you to grab, there's even brand new games being built and released on ZDoom[0], with aesthetics ranging from "this feels right at home as a Doom game" to "a Doom engine game has no right looking this good" to incredibly stylized, unique takes.
Nightdive did a nice job giving new tools to make modern mods possible (effectively giving us much of the kit they used to remaster Q2). My read is that this isn't an accessibility to be able to make cool mods problem so much as an inertia one.
Have to say I have a lot of respect for Nightdive after finishing their System Shock remaster. It was faithful, but modernised, and none of the tension or horror was lost in the process. It remastered a 30 year old game but didn't make it unrecognisable, just gave modern gamers an old-but-new immersive sim to enjoy (which are few and far between). Lots of younger gamers get to enjoy the series with modern advancements in UX.
