It's a good idea, but I don't think it's worth implementing at this
point, given that Mozilla will soon provide us with a
strings_all.tar.zst tarball per release, which will include both Firefox
and Thunderbird l10n data (it'll be available along the releases
tarball) [0].

This will obsolete all this tedious work of keeping hashes up to date.
