Merely pointing out it's not a spec. But yeah, it's older than me :)

If magic were smarter (was able to derive from syntax or had regex
capability in the format), it could've still told me I was looking at
a script (and not just a bunch of text - which is next to useless). It
doesn't, so arguing that magic could be used (not an argument I've
seen, but one I was expecting and figured I'd preempt) instead of an
extension is lacking.
