NACK. I think the direction of this change makes sense in isolation, but interacts too badly with other default mempool policies.
Users will always prefer to transact at the lowest fee given the current demand for tx confirmation, and miners will always prefer to earn more fees by filling blocks with extremely cheap txs rather than mine half empty blocks. Both these market forces are set to intensify over the long run as fiat inflation goes on and Bitcoin's block subsidy runs out. I don't eve

tACK 4b80147
Confirmed the test passes and mocktime is handled consistently within migrate_and_get_rpc.
Reproduced the failure when mocktime is set redundantly and confirmed the fix removes the race. Clean change, and no unnecessary test logic outside the migration function.
Good to go from my end.

I think it makes sense (as a default) to always include things in blocks if they're in your mempool. Otherwise having those txs in your mempool potentially blocks you from seeing txs you would include in your block (eg, double-spends that don't pass rbf rules), and seems like something of a waste of memory/bandwidth (though not a DoS risk).

I think that's fine -- if `require_standard` is true, then undefined program types will have already given an INPUTS_NOT_STANDARD response; if it's not true and #29843 has been merged, then we'll accept any witness including a null witness for undefined program types, so `RequiresNonEmptyWitness` should return false for them. That can change to true when they're defined in a soft-fork, but that's soft-fork behaviour, so should be fine.

Just two test vectors? If there's more then it might make sense to put them in a JSON file.

> You cannot make a constructor noexcept if it fails to establish the invariant of a class.
The question of how to handle constructor errors has been annoying me in this code base for a long time. We do everything from throwing, to output error parameters, to factory functions returning optionals, to `bool` operator style validity checks. My feeling is we recently tend to avoid throwing exceptions, my personal preference would be using c++23's `std::expected`, but that will take more time to

⚠️ sagarkarki99 opened an issue: "spendable is true for UTXO of private key disabled UTXO"
(https://github.com/bitcoin/bitcoin/issues/33110)
I have a private key disabled descriptors wallet which I use to watch transactions. Upon fetchings the UTXOs using `listunspent`, the spendable is true. Documentations says: `"spendable" : true|false, (boolean) Whether we have the private keys to spend this output`.
Shouldn't the spendable be `false` for this case, as it belongs to wallet where there is no private keys?

I don't think that's possible, because `block_to_connect` points to a `const CBlock`, so we can't pass that to `ReadBlock()`.

I followed ajtowns suggestion and moved the logic to `policy.h` as defined in the patch below. Instead of `RequiresNonEmptyWitness`, the function is named `IsNonAnchorWitnessProgram`. This way, returning `true` for undefined program types that are non-P2A witness programs still makes sense.

In 8a08eef645eeb3e1991a80480c5ee232bfceeb37 "tests: Check that the last hardened cache upgrade occurs"
An argument can be made that sqlite3 is imported every time this function is called, for which an alternative could be to import once at the start of this file and use the corresponding boolean, like it was done in this PR previously. The import would still be limited to one file unlike it was done previously.
But I don't think it's a big deal and the current implementation looks fine to me.
