Anything other than strict `</module` is not going to fly.  An
argument in favor of keeping `</script>` is that bundling tools and
minifiers already know about avoiding `</script` -- using another tag
name now means that a conservative tool needs to avoid another magic

Hear hear.

Not going to happen, IMO.  The HTML spec does linefeed conversion
before any part of the tokenizer even sees the characters.  And \0 is
banned in HTML for good reasons.
