Unless Firefox has changed since the last time I touched the codebase, I'm
pretty sure that it has all the Rust crates vendored which it needs. So,
Firefox alone shouldn't be a problem.

I think Rust projects will always tend to vendoring, because the huge
micro-dependency style system that exists means we'll never keep up trying to
package these. Kanidm has ~200 crate indirect dependencies on it's own, I
can't imagine how many firefox has. It's a waste of our time to try to
package all 200 when we could be putting that time into other things instead.
This essentially means we are always at the whims of those vendored
dependencies and what they require, and that is highly likely to be the
"latest" stable compiler.

I think we should aim to:

* Have rustc/cargo move with the upstream cadence, with automation as
suggested into all SLE/LEAP/TW/Other
* Do not attempt to package crates - only package leaves IE consuming projects
* Improve our rust macros and packaging guides around this topic.

As much as we want to wring our hands and slow down rust, and do things
"our way" we can't - we have to follow and adapt in this case.

I wonder whether for packages requiring rust it would be most sensible
to package up all dependences into the package itself - that at least
ensures a "stable" set of dependences for individual packages even if
it means that a dependence might exist twice in different versions in
different packages.

Not sure if that also means packaging up their own rust as some
package up their own clang/llvm ...
