Allow renaming of an account

It’s tedious to have to delete and recreate it just to change the displayed name (it wouldn’t bother me if the internal naming was fixed - I just want to change the name I see)

Specifically I’m referring to CalDAV calendar accounts - I don’t know if it’s the same for all accounts or not.

actually, you can change the name in tools->accounts in the General tab

I think you might be referring to an email account. There is no general tab for a CalDav calendar account.
