Hi,
While I agree with the arguments in favour of (optional ANYONECANPAY) APOAS in
lieu of CTV in the short-term (given the additional benefit of enabling Eltoo),
there's a point to add in favour of CTV (or similar) in the long-term beyond as
an optimisation.
With APOAS-based covenants, the

Correction: thinking about this some more, you can't actually expect to
have a stable txid if you allow additional inputs at all...
So yes, amending BIP 118 to commit to sha_sequences (which indirectly also
commits to the number of inputs) as proposed in the OP should be sufficient

I thought the changes mentioned in the OP (+ committing to the spent input
index) only solves the half-spend problem, but not the stable txids one?
There can be other inputs with a scriptSig, which doesn't get

Hmm? You can't have channel factories without Eltoo. (Well, you

I think we're both right. You're also right that there are many possible
configurations including the one you mentioned. I can see good reasons to
use multisig even if both keys are quickly on
Here's a summary of the trade-offs I see for using APO as a CTV alternative:
1. The resulting txids are not stable.
CTV commits to enough tx information such that given the txid:vout of the
covenant-encumbered output, you can predict the txid of the spending tx

In my view, the point of a vault is the ability to keep your primary wallet
keys in *highly* deep cold storage (e.g. metal backup only, not loaded on
