I still have a personal dislike against a spec that lacks a "scope" or
any other useful introduction part.

XDG_CACHE_HOME is for "non-essential data". I have some doubts that
the DVDCSS cache belongs there.
Since the keys for some very short/simple (never investigated it, but some
titles from the Australian "Spaceballs" edition show this effect) titles
cannot be cracked, deleting might mean some DVDs will no longer be playable
if the drive region code was changed at some point.
