I don't think so.

What you think doesn't really matter in this case: it *does* just work.

As I have recommended ages ago, I think it would be much
better to move those resource forks into a separate tree, rooted (using some
*QUITE* distinctive name) in /tmp.

"QUITE" distinctive names aren't good enough, because sooner or later, someone is going to stumble across that name. Also, I don't see how going to /tmp/ helps. As a matter of fact, I see going to /tmp/ as rather problematic. What if /tmp/ is a different filesystem?

When unarchiving to HFS, the "macgnutar"
would catch this special name and restore resource forks.


The reason is simple -- to make the archive easily and without confusion
useable worldwide. Should you try to unpack archive of your design on, say,
Linux, you'll get a pretty mess.

Not true. You will get warnings from tar but the resource forks will simply not be untarred.

I have actually implemented this and tried it.

OTOH, should you unpack there "mine", you'll
get only some trash in /tmp, where it does not matter,

I think no trash whatsoever and warnings on the console are a better solution.
