It's really, really hard to beat the user-interface (or security!) of a traditional light switch or dimmer. I'd like to have control without getting up, automate some things, or change the colors, but that all comes at a huge cost.
The former isn't something which is happening yet anywhere that I know of (in the UK at least, even in new-build houses), and the latter needs pressure from consumers which isn't happening for anything in the internet-of-things space yet :/
(edit: don't try to use markdown in HN comments, however automatic it has become for you :)
I've just bought an apartment in mainland Europe and the live and neutral go to the switch, and from there two wires go to the rose.
In new buildings (~1970+) I've always seen what I consider the standard: live hot and neutral to the switch. Hot is switched to the fixture, and neutrals from both sides are tied together in the box.
