I hate that one too but each to their ownI wonder if you could just open the little case up and link the switch mech, i bet that would be quite easy to do and would give a recessed look.
Perhaps i obsess too much over detail like this, but i spent ages and a fortune getting our main door and hardware including bell push just right. I think a good front door and high end hardware really makes a big difference to a house.
Fair enough, but I'm not overly fussed by a white 8x2cm box stuck on white door frame

I've learned it's all too easy to get worried about things, that 2 weeks later you don't even give a second thought/look at!
The alternative is to have a tradition push with a wire, but then that needs to be run to the box inside, so you have a wire showing!
