These are still very common in Sweden. I installed one when I renovated my kitchen a couple of years ago for example. Different design of course, but the same mechanism. 2 out of three bathrooms have similar ones too! Iirc the shower in the guest house does as well, but memory is fuzzy and I'm currently too far to check
Not common for showers, though. Those almost always have separate temperature and flow controls.
When shopping for a home in Sweden, seeing a kitchen without single handed faucets is a telltale sign that the whole kitchen was designed with form prioritized over function.
