Seriously, my bank used to have a password requirement that was 6 characters exactly, no more or less. Plus symbols were completely banned. The reason, it was also your phone password, so in reality it was a 6 digit numeric password where they interpreted the T9 letters as numbers.
I use mold for everything, but don’t really bat an eye at using mould for the tool that is used to make parts which I see pretty often through my work.
