You're completely wrong. The presence of BOM or not is very important
for some applications, such as Firefox (not to determine the charset,
but the MIME type of local files).

It can be repaired, but the problems are the user doesn't know
what's going on and this breaks things. If some package removed
the execute permission of some utility in /bin, this would also
be a grave bug, though it can easily been repaired.

Firefox. And that's actually the way I detected the bug, after
hours of trying to find why it was behaving in an inconsistent way.
