I suppose if someone found a technique in the wild that defeats regular ASLR (even if only sometimes), they could then test that same technique against fine-grained ASLR and evaluate if the FG ASLR was more effective at preventing exploitation.

Any classic buffer overflow/stackssmash can defeat ASLR, it just might take a long time to get lucky guessing addresses. Couldn’t we Monte Carlo this?

Maybe take a known vulnerable exec, create a fuzzing attacker and run it both ways seeing how long it takes to get lucky a few times. The more secure version should take longer.
