But many OS X apps (even some from Apple?) don't set the Finder info, 
relying on OS X's preference to determine type from the file type 
extension in the name.

But okay, it's not a bug per se.  My main point there was having fun 
with the notion that no vendor except Rev has ever shipped any software 
with known bugs. ;)  Of course there are enough examples that we needn't 
stretch to find more.

I still feel it would be useful to allow users to be in control of these 
additional files.  It makes it cumbersome to use any non-Apple Flash 
drive, work with multi-platform networks, etc.  Not allowing that 
control just makes Apple look bad, lending credence to the old lightbulb 
joke:
