I say go for it, push the latest one you feel is ready into testing - you'll have my vote (especially if this is the latest version from Devel, since that's what I've been using a lot lately, and can vouch for it being just fine for the testing criteria), and I suppose it is frustrating to have your votes negated, but really, that comes with the turf of being an actual software tester. New stuff can have new unknown effects, etc. I also suggest putting links to the testing packages queue at the beginning of the thread, because I know there's plenty of users who just don't know where to go to vote, but wouldn't mind voting.
