Actually it looks like Slush is finally signaling BIP91 so I don't have to switch

Good job Slush!

Great stuff. He saw the writing on the wall. Right now it would be suicide to NOT run BIP91 now that it's a certainty.
Yep!
I still see Bitcoin.com mining BU blocks though. Hope they enjoy their invalid blocks!

Kano doesn't plan to switch daemons?
I have nothing to do with him nor communicate with him so he cannot help you with your query

Meanwhile - a few minutes after I switched over to the BIP91 code ... after doing proper testing of the block code ... we found a block ... so your question is answered
