If you quested in Duskwood, they administered a type of "cure" to Sven, who was a newly turned worgen without his insanity. This "cure" enabled him to become a mostly sane worgen, if not as good as the Gilneans.
I think there are tons of plausibilities, but the most cemented ones are found through questing. I think the worgen in Duskwood that aren't sane can definitely turn others into worgen, but the Gilneans will come into play and try to help these insane worgen become sane.
A lot of people don't like stereotyping under the race they've been given. Playing a Gilnean who's been bitten is really too boring to some people. As long as its played correctly with proper lore behind it, it should be fine.
I may not have gotten the whole question in your post about that, so if I missed anything, tell me. :P
