By adding annotations to the method, mypy now raises this issue. This fixes a TypeError when a Distribution's old included attribute was a tuple.

@Avasam, how about this for the deprecation of sequence?
After a quick search on github, I do see people accessing it, so we cannot simply remove it...

I had opted out of wanting to replacesequence by typing.Sequence in #4575 (comment) because there's a lot of implications when it comes to new checks and supported types (like having to explicitely check for str first everytime, because a str is a valid Sequence[str], both at runtime and in type-checking).
Not to say it wouldn't be an improvement, just that's not something I wanna go into for the scope of those PRs.
Is making sequence private something you want to do independent of those changes ? If so, this commit is fine yeah.

I think so. It seems to be such a trivial implementation detail, I don't know why people are importing it from setuptools.
It is probably good to deprecate it now just in case at some point we decide to remove it.
