Criticism for Foundry aside, it's an extordinary effort to implement a mature self-hosted alternative, especially as FOSS implies it's going to be a side project for most if not all of its developers.

Foundry's upside is that it's extensible (modules), which increases traction and nurtures a community.

Most of the FOSS attempts will probably die if they won't take that approach (extensibility that is).

Yeah that's how I see how it would work. Just build a framework for the players to interact in according to the basic mechanics of tabletop games and then expose a rich module API and hand it off to users. If you're clever about it I could imagine you could machine-translate the art asset formats made for Foundry, or design it to use it directly.
