But you're right, taken at face value, you can't so much as refer to
"roll Strength + d20" without infringing.

Right, I suppose you could write an OGL-only product that included parts of the SRD and go through the incredibly clumsy procedure of changing all references to "d20" to "twenty-sided die".
Outside of a more explicit reference to claiming "d20" as PI when used in the title of a work, however, they've just scooped up the entire standard game term into PI. It almost smacks of PI'ing the word "dice". Sure, I could get around such a PI designation by using the term "polyhedral variance generators", but it's nothing short of foolishly annoying.
