RBF certainly does not break more things than depreciating an entire address
standard. P2PKH addresses are still used by old wallets, and it's often not
worth the risk to upgrade to new software for old coins kept offline by
ordinary users. I personally have used P2PKH addresses in the past few months.
Zeroconf on the other hand has never worked reliably, so you can't even claim
it's a "supported feature". And the fact is, it breaks all the time because
every time miners change their acceptance rules - eg with new releases - we
break it every single time we do a new release with different you can easily
exploit zeroconf.
Frankly, the fact that we didn't widely implement full-rbf sooner is quite
unfortunate, as Bitrefill, Muun, etc. should have never been using it in the
first place.

It's clearly false to claim that the "majority of bitcoin wallets and services"
are using zeroconf. A tiny minority are attempting to use it, with the vast
majority of previous users having given up on it.
