For further monitoring, I've set-up a mempoolfullrbf=1 node and are
logging replacement events with [0]. I filter the full-RBF replacements
and list the replaced and replacement transactions here:

https://fullrbf.mempool.observer/

This also tries to find out if either the replaced or replacement
transaction has been included in a block upon loading the site. The
yellow mined-in-badges link to the block on miningpool.observer to a)
show the mining pool (if known) and b) see if the (mempoolfullrbf=0)
miningpool-observer node thinks this transaction is extra / conflicts
with the mined transaction. This should be the case if a full-RBF
replacement transaction is mined.

Over the last few days, I has mostly seen OP_RETURN transactions
(presumably mostly by OpenTimestamps; but I haven't checked closely) and
a few other non-OP_RETURN transactions. None of the replacement
transactions have been mined yet.
