Get Mojang to pull in large optimizations. Thus far, they have been uninterested in this (though some controversy over Optifine may have left a bad taste).

I remember that. I think the issue there was it mostly handled badly… It seemed like Mojang was trying to go behind the communities back (which I thought sounded a lot like the way Microsoft does things…so I blamed them instead of Mojang). IMO - if this is an era of more open-collaboration it may be possible for Mojang to benefit from working with the community. (There is an excellent example of this in the way AMD has worked with the Open Source community…)

Pull the changes into a modding framework. Understandably, Fabric/Forge aren’t willing to pull in a huge overhaul they’d have to maintain. Mojang may have similar feelings.

I can see that too… That’s why I am thinking that it might be possible for there to be a more collaborative effort… Like a repository set up where community devs can submit PR’s for changes, and Mojang can either approve or deny them. If that started working well, I could see a situation where there are specifically Mojang employed community devs, the role of working on changes that will help both the main Minecraft tree and the modding community.

(Okay, I am probably more optimistic than I should be – after all Microsoft is in the mix here…)
