CBS killed it, but some (all?) of them are working with OTOY and the Roddenberry Archive now. They had a site up a few months ago where you could walk around the bridge of nearly every iteration of every Enterprise. There were about 30 of them, including speculative designs for some early concepts for the Enterprise.
They haven’t said anything about making a full-scale Ent-D yet, but several of their videos on YouTube show glimpses of a full-scale 1701 refit.
The original project was something anybody could play, and as far as I know if you can find it you can still play it today, and you will be able to forever.
You can’t do that with TRA/OTOY now can you?
streaming-exclusivity is an extremely bad thing.
As for the minecraft stuff, trekcraft exists today, and they have like 4 different iterations of the Enterprise D, with the latest version using a mod to add more detailed blocks and still being worked on today, all the way back to the original.
