I feel like it can be realistic if that person has about 5-10+ years of experience and a lot of time on their hands to keep up on frameworks. But a junior level full stack person, probably not. Backend devs I find usually also do a fair bit of database work, at least at a basic level, and are usually where the devops work comes in (migrations, upgrades, keeping the system running). As experience grows, I think most people at least get a sprinkling of these different fields, even if they didn't intend to.
