The vague convention, as far as I understand, is that Ex denotes an extended variant of a function for more advanced use cases (e.g. with additional parameters/options) which is functionally a superset of the original function, whereas numbered versions are intended to be complete replacements and/or may change the semantics compared to the prior version.

I agree.
