Will Rust be able to switch to it completely as to cut out relying on glibc on Linux for example?

There are important reasons why Rust should continue to use glibc by default, but the Rust compiler already supports musl libc on Linux, so glibc is not required.

To be more compatible with system code?

That’s one reason. Another is NSS:

http://www.gnu.org/software/libc/manual/html_node/Name-Servi...

It’s a mechanism in glibc for loading dynamic libraries at runtime (based on a config file) to handle DNS and some other things. Anything statically linked can’t support this, which can cause issues with some setups.

Yes, that would be possible.
