[New-bugs-announce] [issue44521] str.removeprefix(): add strict: bool

[Марк Коренберг]

New submission from Марк Коренберг <socketpair at gmail.com>:

#39939 introduced .removeprefix for several classes. I propose adding kwargs-only parameter `, *, strict: bool = False`. It should raise some exception (I'm unuse what exactly) if the string DOES NOT start from specified prefix. False by default only for compatibility purposes. Personally I think it should be True, but I understand why it's impossible to change API.

The same about `removesuffix()`.
