Concept ACK, thanks for picking this up! Needs a rebase and squash.

@michaelfolkson gave me a tip in my first PR that might be helpful for you:

You can do a reset on your branch to the current top commit on master, then re-adding your commit and force pushing.

git reset --hard insert_current_top_commit_hash_on_master

Then add a single commit on top and force pushing

Concept ACK

Did you consider also doing:

I think the simplest parent witness script to create same-nonwitness-data txs would be OP_DROP OP_TRUE, with a different arbitrary witness stack element in each child transaction. OTOH multiple script branches are far more realistic, I guess that's the primary scenario :)

(#22253 (review))

Concept ACK

Thanks for picking this up and welcome as a new contributor! 🎉
Happy to review/test as soon as the CI is green :)

(Also needs a squash)

post-merge ACK 91b0597 🍺

nit: not a big issue, but next time, please take care of the commit message body, the 4x"Improve mempool_accept_wtxid.py" doesn't contain any information :)

Oh yes, thank you for the guidance. Will certainly take care of that in the future.
