Photo logs were accepted as proof of visit for virtuals, and as far as I know still are for the relatively few remaining virtuals. I see no reason why it should be different for earthcaches, and as Matt says this new guideline does seem ill conceived and ultimately damaging.
Edit to add: When I say "proof of visit" I mean sole proof of visit.
