Hopefully not. There shouldn't be a "dominant" browser in the "market", there should be a huge mess of choices available. If there is a "dominant" browser, corporations will cut corners and target it directly. They shouldn't be able to get away with that. Browser diversity means they cannot afford to single out users as irrelevant and unworthy of support. They should have no choice but to support them all.
