I think the convention can stay as-is, so the script can hopefully pull out the categorization from the bracketed strings at the beginning, and if the text after those is plain text that’s fine... but if someone uses *emphasis* or something like that, it could be preserved that way in the output if we don’t make any effort to strip those, and then it’s markdown right?  A naive word-wrapping algorithm wouldn’t care either.  Markdown is basically a standardization of old plaintext conventions from email (and probably from typewriter conventions before that), so it tends to happen naturally without necessarily thinking “oh I’m going to write markdown now” and consulting the specification.  I’ve seen commit messages with valid bullet lists sometimes.  So if we say that markdown is ok in git commit messages, including changelog stanzas, probably there’s no harm?  And if we don’t say it, it tends to happen anyway.
