Rust is just getting started to see the same problems as C in the 80's (becoming successful enough that multiple competing compiler implementations emerged, which in turn required standardization). I think that the same will happen with Rust (but those can be good things, if it works more like the C committee and less like the C++ committee): first multiple competing implementations (like gccrs) will emerge, and once the situation gets too messy, a proper specification followed by an ISO standard, and a committee to carefully refine and maintain the standard.
In the 80's there wasn't internet, which is a huge help to centralize power. For example, look at Python that got popular after internet was a thing: CPython IS Python. People tried alternatives, but popularity brings even more popularity. The same thing happened with Deno recently. Sure, maybe it has a bit of traction, but it's almost nothing compared to Node. It will be the same for Rust and alternative compilers: nobody will use them outside of a few people, that will deal themselves with the consequences.
