Your perspective is too limited.  Linux-based systems are very popular,
but they're not the entire Unix world.

# hostname -f
# hostname
-f
# hostname minea.eeg.ccf.org
# 


Personally, I don't like hostname returning a FQDN, but many other
people *do*.  It's common.  When I work on a system that's set that
way, I leave it set that way.

It's so common that bash has two different PS1 escape sequences to
handle it.  Has had them for decades, as far as I know.

There is nothing "wrong" about this configuration.  I don't like it,
and you clearly don't like it, but our opinions only matter to us.
