Since uBlock isn't a web standard (and runs on a constantly-shifting set of heuristics), it's unrealistic to expect devs to chase it successfully. To be sure, they will chase it to maximize user eyeballs, but expecting that to be the correct course of action is like expecting devs to adapt their sites to IE6 quirks.

I thought we went through a whole standard development process to get away from the need to handle user-agent issues.
