I think knowing about frontend is important for a senior or higher level engineer. I would expect someone at that level to be able to contribute where necessary, and know enough to make sane decisions and know when those decisions impact backend/frontend. But to be equally good at both isn't reasonable

A backend engineer that has adequately put in the time to operate at a senior level, will more than likely have worked closely enough with FE to check those boxes. They should be familiar with technical design and processes, which if done effectively, teach an engineer to ask those questions.

"I'm capable of not making a fool of myself with UI" does not equate to "I'm a full stack developer"
