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.
I think I agree with that. From Block 684317 that was mined 10 hours ago to the recent block mined when I posted this, Block 684368. It will be noticed that BTC.com is not fully signalling. Also if Rawpool can signal, it will almost make all new blocks mined to be part of blocks that signal for taproot activation.
Block that did not signal right from block 684317 to block 684368 that was mined a minute ago
