We had a similar situation when we decided to fix the incorrect quoting in the `author-script` file, and we decided that we have to be careful: https://lore.kernel.org/git/nycvar.QRO.7.76.6.1807271415410.10478@tvgsbejvaqbjf.bet/

In light of that, I think we should go with Jonathan's patch for a couple of versions before tightening the reader side again.
