...and now Poolin might be mining full-rbf too: https://mempool.space/tx/2a2dfacc7d96706972a5b3362fc1d8253d43a03f89b0b0da525363788672810f
Looks like another pool may have turned on full-rbf: https://mempool.space/tx/80f9630855e26aed27f1e6ab124da8303f8e2a904d665c4999c9db385ad14ff1
So that's Luxor, AntPool, Binance, EMCDPool, and possibly now ULTIMUSPOOL.

I think we can confirm that Poolin is mining full-rbf. I've seen a bunch more txs mined, eg most recently: https://mempool.space/tx/d830cb38f2636c6a9105fd4d532eecee2d92d609bdc93ce29ed88154a695471a
