The design behind yggdrasil is to keep as much the same as possible. I have some projects running on ygg using simple, existing, TCP-socket tech. Works great. So, to get the big issue out of the way. There is a lot of compatibility already there.
The gateway possibility is there, someone needs to do it, is all. There are instructions on the website on how to setup such a gateway on your local router, so you do not need to install the binary on each device to access ygg services.
The main reason why there isn't really anyone really doing this is that this is a research project and most people that use it, use it for their own usecases. Not to offer some websites which aren't already on mainnet.
