i don't think changing the locale data or forcing titlecase everywhere
makes sense.  the data is already in the standard format that users
expect for their locale.  having a flag to support that seems like a
good way to get developers to naively enforce their own expectations
onto users.  "my language writes things like 'Dec', therefore every
language out there must use titlecase".

forcing to all uppercase or lowercase seems a bit more reasonable in
certain outputs (everything is upper/lower case beyond the date).

we already have a flag to force it to uppercase.  makes sense to have
a flag to do the opposite.  your arguments here apply to the uppercase
flag too.
