Sure, but if someone came at the C-centric ecosystem today and said "let's do the work to make it so that any language can play in this world", then surely "just FFI through C" would be considered rather underwhelming?
In my opinion it's an overengineered boondoggle, since "C APIs ought to be good enough for anything", but maybe something useful will eventually come out of it, so far it looks like it mostly replaces the idea of C-APIs as lingua-franca with "a random collection of Rust stdlib types" as lingua-france, which at least to me sounds utterly uninteresting.
