RBF certainly does not break more things than depreciating an entire addres= s
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 mont= hs.

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 th= e 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 easil= y
exploit zeroconf.

Haven't heard of = any release breaking zeroconf. I would absolutely say it's working reli= ably.
=C2=A0
Frankly, the fact that we didn't widely implement full-rbf sooner is qu= ite
unfortunate, as Bitrefill, Muun, etc. should have never been using it in th= e
first place.

You make it sound like we&= #39;re the odd ones out when it's in fact ~every service that lets you = buy stuff with bitcoin. It's just that we're the only ones raising = voices on the mailing list so far. On the contrary side, can you name one s= ervice that lets you buy stuff with bitcoin that doesn't rely on zeroco= nf? Maybe with the caveat that it should have some level of scale and an au= dience not consisting of only power users.

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.

I didn't claim that. But it's definitely true that the v= ast majority of wallets and services do not allow users to do RBF. This is = easy to validate as the list of wallets with RBF support is short), the lis= t of exchanges with RBF support is zero.
29% of txs signal RBF, meaning 71% do not. And let's be honest, it= 9;s not like the majority of those were given a choice and chose not to, fo= r the majority their wallet just doesn't support RBF.
