Yes but I think it should be included until it is not supported at all
anymore.

Keep it on rust@1.44. Even though guix refresh --list-dependent will
report not many dependents, changing a current rust version would
trigger many rebuilds. There would be enough rebuilds to require it to
be applied to staging.

I've also attached a work in progress patch to add rls as an output,
too.  I would love if all the "extended" tools can be included. Some
tools like clippy and the rust-src component would be very helpful.

One other thing:

> +      (outputs '("out" "doc" "cargo" "rustfmt"))

should probably be: (cons "rustfmt" (package-outputs base-rust))

to be more resistant to changes to older packages.

Best regards,

John
