Recent language features seem to be suffereing from excessive parenthesisitis.

Agreed. Mandatory parentheses purely for readability are ultimately futile - I bet I can write unreadable code even if the parens were required :-)))))))))))))))))))))))))

The parentheses around genexps were (AFAICT) different - without them, the grammar was ambiguous, so some way of disambiguating was needed.

+0 for mentioning parens around conditional expressions in PEP 8. But it's aready covered by the general "code should be readable" in my view.
