Happy to leave the decision to you.  Either of these options sounds good
to me.

It's not just "looks safer"; it's a matter of correctness.  The content
of ${_args_cache_foo} need to be escaped once for their transit through
lex.c when _foo will be read by compinit, and once against «echo»'s
treatment of backslashes.  Thus, «print -r --» should be used _in
addition_ to ${(qqq)}, not instead of it.
