Yes but nobody considers the cost/benefit of having that over a specialist with the same amount of experience.

What takes longer? A full-stack guy trying to figure out how to work around some obscure front-end quirk (like the restrictions on overflow-x/y resulting in unexpected computed values, or the fact you can't transition to or from computed heights?) or a front-end specialist learning some basic dev-ops, or how to change a few Django models?

"Building something" in a language/ecosystem should be easy for any competent dev. I've never touched Obj-C or Swift in my life, and if you asked me to go release an iPhone app on the app store in my spare time in 3 weeks I'd be 100% confident that I can do it; but if you asked me to go and take a job as a senior iOS dev straight after that, I wouldn't even be confident to put myself forward for it. I probably wouldn't even put iOS on my resume.

I think as a senior tech person involved in the hiring process, I should be doing a better job of identifying exactly what I need and finding the right person than just going on the hunt for 6 "good devs" and hoping everything falls into place.
