Since file is essentially meant to be interpreted by a human (no
utilities, apart from systems like MailScanner ever try rely on
file... Purely informational stuff, not really "system-level", IMO),
it is perfectly fine to edit the magic file to suit your local
situation.

That some file formats are less than well endowed, in the "magic"
department, is a very tired old thing... Not much to do about that,
apart form "fixing" it for ones own situation.
