.... and I’ve heard rumors that maybe Maya could integrate and provide support for those projects that were building on Terra.
You mean help those severely affected projects to migrate easily? It's a good marketing strategy for them if that is the case. It's still up to the developers if they want to take that offer. My guess is that most of them will continue to build on Luna. They are just waiting the result of the voting and the implementation of the revival plans.
While it would take time I think it is a better idea to jump off the sinking ship that is Terra Luna and for the developers of those projects to find an alternative blockchain in which they can release their project, however the real question is if those people actually have the expertise to do something like that? Because as we know a great deal of the developers that create coins do so only for the money and they have no idea of how to accomplish something like this.
