If that's package.el's `wanted' feature (default in
~/.emacs.d/elpa/gnupg), it does not harm to system. I couldn't
figure out why not just use system default location.

Similarly, SSL certificates (of mail servers) are stored in
.emacs.d/network-security.data insead of ~/.gnutls/known_hosts

GnuPG does allow multiple gpg-agent insances. You can check that
by:

1. list-packages in Emacs, then an instance created under
~/.emacs.d/elpa/gnupg;
2. C-x C-f to opens a gpg file, then another instance (system
default one) created under ~/.gnupg/
