Let’s call this BIP 451. Please add the number to the preamble, set the Assigned header to today, rename the BIP file, and add an entry to the README table.

Yeah, thanks, adding separate commits without squashing them during the review phase is preferred.

The Preamble updates and table entry look good. Thanks for the quick turn-around.
Given that you said that you are still mulling over some of the review comments, I’ll leave the “PR Author action required” tag for the time being. Please let me know when you’re ready for another review.

@murchandamus this one is ready for another look. In 686c1b0 I updated it to use only OP_RETURN "ash" and some other small edits.
