visibility_of_all implies it only returns elements if all visible

• By placing an X in the preceding checkbox, I verify that I have signed the Contributor License Agreement

This is not what the function does.
visibility_of_any in my opinion correctly conveys the usage of this expected condition.

If you're gonna change the name of this class you should also change the tests that use it.
You can find those at https://github.com/SeleniumHQ/selenium/blob/master/py/test/selenium/webdriver/common/webdriverwait_tests.py

shouldn't call return a boolean?

[rouke-broersma]

This is clearly not the author's intent and returning elements instead of a boolean is not out of line with the rest of the expected conditions.

See presence_of_element_located: https://github.com/Mobrockers/selenium/blob/f878b53d9dd66ef25444b82e50218acd36f6bc4e/py/selenium/webdriver/support/expected_conditions.py#L49

etcetc

Or do you mean as a final condition if no visible elements van be found by the given locator?
In that case perhaps you're right yes.
