I would suggest clarifying this by adding the sentence:

"Systems should NOT however, rely on HTTP GET to be 'safe'"

Advising otherwise would be misleading, particularly in the case or URLs
with query strings.  There is a reason that most web crawlers, many
other caches, etc. exclude URLs that have querystrings -- the fact is
that most systems do NOT depend on *all* GETs to be "safe".
