I can't speak to RPM, but Debian's arrangements for avoiding crates.io
downloads at packag-ebuild-time will work just fine even if it
the cargo calls are buried inside meson.  All that would be needed is
a way to disable any source replacement done by qemu (see previous
mail) so that Debian's source replacement takes effect.
