This isn't "dead code" on a Debian "bookworm" system where I'm testing
with:
$ rustc --version
rustc 1.63.0
With this commit in place, I get:

Some errors have detailed explanations: E0631, E0658.
For more information about an error, try `rustc --explain E0631`.
error: could not compile `generic_format_parser` due to 2 previous errors
make[3]: *** [Makefile:431: debug/liblibformat_parser.a] Error 101
make[3]: Target 'all' not remade because of errors.

With this commit reverted, the build again succeeds, with good test
results. May I, therefore, push a (partial, I suppose?) 'git revert' of
this commit?
