Whether you want to or not, it's your choice. However, the push towards DevOps as opposed to Dev is based on efficiency; it's easier to hire a developer that knows operations, instead of a developer and an operations employee. Even without DevOps, a lot of positions are Full Stack, so you need to know front and back-end development and technology. I don't think it's merely a trend, it's more or less a push towards saving money and time. If you don't want to be a full stack eng or a DevOps eng, then you're limiting yourself and you're limiting the opportunities you'll have. It sucks for those who want to limit themselves to one specific group of tasks instead of branching out, but it's just how it is.
