It's possible by modifying 'bootstrap-guile-url-path' and
'bootstrap-guile-hash'.  Apparently, some architectures already
use a newer guile.  E.g., aarch64 has 2.0.14.  However, this
probably would entail a world-rebuild I think, so this probably
needs to be done on core-updates.

Why limit to guile 2.0.10, why not go for guile 3.0.7 instead?
I don't kow how one would go about updating the bootstrap binaries though.

Anyway, there have been quite a few bug fixes and new features since
2.0.9, and updating to guile 3.0.? would allow dropping some compatibility
code in various guix/build/, so I wouldn't be opposed to such a change.
