You could say the same about C library dependency hell. I have not used FreeBSD myself, but if I'm remembering correctly, the main reason that dependency hell does not affect the BSDs is that they have their own internal set of C libraries that are developed in tandem.

As an OS vendor, FreeBSD could do something like that with Rust. If a Rust application is developed inside the FreeBSD source tree, make it so that it can only use the Rust standard library plus whatever libraries exist inside the FreeBSD source tree.

Just like any UNIX proper, the ways of GNU/Linux are the exception.

And non-UNIX OSes, where by definition C library belongs to the compiler it is shipped with.
