How Has This Been Tested?

Also standardize all all's as sorted tuples along the project.

Any links to this standard? As far as I know, it must be list of strings.

https://docs.python.org/3/reference/simple_stmts.html#the-import-statement

The public names defined by a module are determined by checking the module’s namespace for a variable named __all__; if defined, it must be a sequence of strings which are names defined or imported by that module.

It doesn't matter that they are lists or tuples. But tuple was already used in types/, so I decided use it everywhere for increasing consistency.

I can't remember which linterish tool used to complain about type of __all__

seems reasonable and lgtm!
