I understand that the current rust-1.65 is unusable by itself because it
misses some part as explained by <https://issues.guix.gnu.org/62064#5>.

However, I do not understand that…

How 1.60 could be the latest compared to 1.65?

Said differently, why 1.65 is packaged if it is unusable?  Even, what is
the point to maintain 1.61, 1.62, 1.63, 1.64 and 1.65 if they are
unexported and unusable?  These 5 versions are not part of the bootstrap
of 1.60.

If the work for updating the Rust ecosystem is a work in progress and
this work is currently in the middle, why is it not done in a dedicated
branch?
