When submit is turned off, a block can be generated and returned as hex, to be used for further tests. For example, it can be submitted on a different node, on a different interface (like p2p), or just never submitted and be used for other testing purposes.

Requested by @instagibbs, I believe, in comment #17693 (comment)

This work is based on the generateblock RPC added by @andrewtoth in #17693

generatetodescriptor will be available for at least 2 releases. Is there any concern that other users will depend on it? I suppose workarounds for it are easy enough.

If anyone was quick enough to add generatetodescriptor to their test scripts, they are surely quick enough to pull it out again the next time they update their node to a new major version.

Does removing the generatetodescriptor RPC require a deprecation cycle?

I'd say no, because it is only used for testing. See also #18933 (comment)

I haven't used generatetodescriptor myself, but I would imagine a use case would be to mine transactions in the mempool with it. With generateblock a user has to manually add all txids to get the same functionality. If we are replacing it, should we also add an option to generateblock to mine the mempool?

Ok, that can be done as a follow-up. Dropped the last commit faefc21 because it was too controversial.

The comment this is based on (#17693 (comment)) suggests to bypass validity check. However, https://github.com/bitcoin/bitcoin/pull/18933/files#diff-9651347c8e00bed3ddc7631de569406dL364 still does that. Do we want to skip that check as well?

Should be trivial to add in a follow-up with a one-line patch, if and when needed?
