Changing this in the PEP will make an absurd amount of code which is PEP-8 compliant no longer so.

It depends on how we change it. There's plenty of room to compromise between explicitly mandating all caps and explicitly forbidding all caps. We could simply remove the section that says to use all caps for constants. We could replace that section with a statement that while it's discouraged, it doesn't violate pep8 when used for constants. We could change some of the documentation (especially around enums) to show non-all-caps style is acceptable. etc.

I'd suggest violating PEP-8 instead of trying to change it.
