This need not be `RecursiveMutex`?

mutable Mutex m_nodes_disconnected_mutex;
```

This could be called concurrently by two threads for the same `CNode`.

Same double-free as above (even though when this code in `StopNodes()` is executed, then the other threads that could access `m_nodes_disconnected` should have been exited by `StopThreads()` already, but better not rely on that).

Yeah. Without the fix commit, the migration process in the test will pass "successfully" and then, at the wallet restart verification, the wallet loading process will throw the "Unrecognized descriptor found" error. Which denotes that t

This is clearly an issue; we should not be inferring descriptors that the code itself doesn't accept back.

On the other hand, maybe we should just permit `addr()` and `raw()` inside sh/wsh/tr. There is discussion about that in #24114 too.

Coding style nit: if you have more than a single line `if` statement, you must use braces and indentation.

Nice, I was asking myself the same question.
I actually started implementing this as a custom, sort of dummy, pubkey provider which had no knowledge of its keys, only containing the key ids, inside the `PKHDescriptor`. So it mapped to the original `sh(pkh(key_id))`. But.. I ended up preferring this approach for the "controversy" that the other one could had.

Just wanted to note that this proposal has some history, see Issue #13477 and the two closed PRs: #13490 and #13713.

In particular, comment https://github.com/bitcoin/bitcoin/pull/13490#issuecomment-398069237 still seems relevant:

I think this is intentional to collect fuzz inputs that fail `SanityCheckASMap` into the qa-assets directory.

This will discard all cases where `miniscript::FromScript` fails? This seems undesirable, because then someone can change the code to add undefined behavior or a crash in code paths that return an error.

Not only that, but if you spend a UTXO that’s the change from the previous transaction with the output of the next, that’s one thing. But if you spend an output with the change from fifteen transactions prior, you may heavily imply that all payments in between were also self-sends.

Wouldn't it be easier to (have an option to) self-sanity-check the match? For example, assert that more than one result was found?
