Replace cargo with something else, then it can become more practical.
See, e.g., the ‘Compiling rust things without cargo (super WIP POC)’
thread on guix-devel@gnu.org.  Once it is complete, rust would have a
build system that works well within Guix, so then we could benefit from
Rust's safety features (and macros, generic types, etc.) without the
downsides of cargo-build-system.  Doesn't change the Rust bootstrap
length though ...
