> What does this framework even do about languages that don't have upper/lower case?

the check is only that it does not start with lowercase. If a language does not have upper/lowercase, it can't start with lowercase.

Yes, the help string for "--from-apt" is wrong in English. That is a bug we (snapd devs) can fix. It should be something like "talk to apt via an apt hook", or maybe "run as an apt hook". That does not make it Ok for translators to one-sidedly ignore the 'This should not start with a lowercase letter.' message they see.
