I can think of lots of good reasons to do it.  For example, making a
mistake that makes the serial number too high, too long, or
incomprehensible.

The purpose of serial numbers is so that slave nameservers will update
properly.  That's all.

While that's a good form of serial number, it's hardly required.  And
lots of places don't do it that way (we do, however).

They're only for slaves.  Multiple master don't have to have
synchronized serial numbers, though they should, especially if you
populate them by copying the files (via ftp, for example); as many
ISP-based DNS servers do it.
