This could cause trouble in the future.
Most of the bits are currently undefined.
Suppose you store some files in a zoo archive, and zoo stores all the
attribute bits as it gets them from the OS, and one of them happens to
have a random value of 1. Suppose a year from now, this bit has been
defined by Commodore to mean "this is a temporary file that should be
deleted as soon as it is closed". When you unzoo the files then, zoo
will restore all the attribute bits, and all these files will get
deleted as soon as zoo finishes creating them.
Or, suppose zoo forces all the currently-undefined bits to zero before
storing them. But suppose Commodore happens to later assign a strange
meaning to the value 0 for one of these bits. You're in trouble
again.
