Can you name any that doesn't arguably qualify as a "further
restriction" already prohibited by section 6 of GPLv2?

That it plugs potential ambiguities is what makes it incompatible.
These are not really new requirements.

Linking v3 and v2-only violates both.  They're mutually-incompatible.
GPLv2 adds requirements on top of GPLv3, and GPLv3 removes ambiguities
present in GPLv2, which some frame as new requirements.
