I've looked at the Ufimptsev-Pytel Pirc and I do think that c6 is a genuinely Pirc-like move that can be played on move three, to which white has many replies. Some of the replies white can make might not attract g6 as the best move. So I think you may be right and that possibly a Pirc can be a Pirc without g6, so I should apologise for being a bit quick and sure of myself. On reflection I think it's up for grabs, with two authorities opposing one another. Sorry.
I found another weird looking Pirc played in the Computer Chess Championship.
Miniature as well
