IMO, that has no value as the OGL can't be revoked. WotC can posture all they want, but they don't have the power to do it.
Whether or not the OGL can be revoked would have to be determined by a court of law.
The original authors of the OGL, the folks working for WotC in the late 90s (Dancey, et al) certainly intended the OGL to be irrevocable and structured it that way. But WotC in 2023 certainly seemed to think they had the ability to do so. The discussions here at the time had folks pointing out the OGL wasn't as irrevocable as it could be, based on the specific language used, lawyerly folks who to some degree knew what they were talking about.
And of course, there are folks who well tell you that legally, we don't need the OGL or the CC at all, as "you can't copyright game mechanics" . . . something also not fully tested in court as of yet, at least not for tabletop RPGs.
The benefit of the OGL was largely a "safe harbor". You could publish under the OGL and feel confident WotC wouldn't sue you with their big legal team. Because being "right" doesn't mean you always win in a court of law, unfortunately. And legal battles are always expensive and often pyrrhic in victory.
When WotC attempted to weaken the OGL, they shattered that "safe harbor", they broke that trust. Putting 5E in to Creative Commons was an attempt to rebuild that trust . . . and it worked for some, not for others.
For the industry going forward, the OGL is functionally dead. Sure, a lot of companies still sell digital copies of their back catalogs released under the OGL, and a few actually still use it for new projects . . . but the OGL is now history. WotC isn't going to try to kill the OGL again . . . because it is already dead.
My only concern when the leadership at WotC and Hasbro eventually changes is that some future version of D&D will not be "open", will not be released into the Creative Commons. But we're probably a decade away from that even being an issue.
