There are plenty of indications that Nintendo considers this release a just as an early on release addressing the enthusiasts who need to have a new console on the first day. They clearly plan to ramp up everything over the course of the year. One could claim that the release is only finished when Mario Odyssey gets released. Nintendo clearly hinted at the virtual console coming to the Switch, its just not there yet. It is probably connected to some of the upcoming online feature (as they talked about offering a different older game with it every month). Nintendo probably equally wants to stress that the Switch isn't a tablet but a serious gaming system. Therefore (and probably just because they are not finished), no web browser or Netflix client now. But there is no reason to assume they are going to be left out forever.
