True, other problems like needless cache regeneration is indeed (still) 
a problem, but, afaik, no solution exists for that, yet.

Main problem *this* proposal is (trying to) address:
The freedesktop.org icon spec only mandates 'touching' top-level icon 
dir, but current packaging guidelines include toolkit-specific (gtk2) 
cache implementation details.  Removing those details without addressing 
related gtk2 RFE yields stale gtk2 icon cache.

I proposed keeping the exising gtk-update-icon-cache as an option for 
icon scriptlets, and this was universally shot-down by the PC.  They 
insisted on simplicity.

So, this led to option 2:
Propose using only xdg-utils.  This simplifies the guidelines, uses 
desktop-agnostic tools, and (virtually) fixes the gtk2 issue, since it 
guarantees that the gtk2 icon cache is (should be!) kept current.
