Mostly I think it's because it's not really necessary for today's phones. Most phones work just fine with VSD sites, the CC team has already verified this so I'm assuming that's why it's not any type of priority. Phones as well as tablets seem to open most sites pretty well without difficulties. Check some other sites and see if they work fine for you (non VSD sites) and it could be that in the end it's because you're trying to accommodate something in VSD that isn't necessary for the most part.
I surf on a Nook Color and I see most sites that people have posted in here in VSD threads (just checked a bunch to make sure before I posted). Not sure why they wouldn't look ok for yours. Got a link? maybe the VSD users can give you some pointers
