This. The past few years I've been a 'full-stack' engineer - which is code for a backend guy who knows frontend. In my personal taxonomy, a frontend developer is someone who cares a lot about UX, and making things look pretty, who also writes code. I've met a lot of these people and they were more than happy to hand over all the infrastructure plumbing side of frontend apps to me - which I did along whatever REST API needed implementing on the server.
