FWIW, it has been available since gnupg-2.0.13 and I confirmed it with
Debian package based on 2.0.14.  You can try it with:

$ echo aaa > test.txt
$ gpg2 --symmetric test.txt # will ask password twice
$ pkill -HUP gpg-agent      # clear the password cache
$ gpg2 < test.txt.gpg       # will ask password
$ gpg2 < test.txt.gpg       # won't ask password

I personally think this feature safer than caching passwords in elisp.
