I'm not sure I would say Stratum is bad, but I would like to see a new protocol at least considered. Now that we have open source firmware for the S9s to activate ASICBoost and mine freely on other pools I think there will be more interest in this sort of decentralization and possibly more interest in pools that give miners more control.

It's worth considering looking at a new protocol at least, despite whatever political pushback may be expected, there might still be receptiveness to it given enough innovation. I'm glad someone gave this one a look. I'm a bit ashamed to say that I didn't even notice this BIP back when it was originally released.
