I think we are there!
All 11 of the top 11 pools are signalling with all blocks. As are 3 other smaller pools.
So voting over 94%.
Assuming no pool changes its mind, and there is no shift in miners to non-signalling pools then lock-in around the 11/12th June is certain to happen.
btc.com is still not fully signaling. My monitoring of them indicates that they are only issuing work that signals for Taproot on 1 out of 4 of their stratum servers. This is consistent with the number of signaling blocks that they have been mining too, as most of their blocks do not signal.
