Yeah, the whole issue seems like one of terminology to me. It's not the case that an X developer has to know Y. It's the case that an X developer that doesn't know Y will lose in a competition against one that does. Hiring, job advertisements, recruiters etc are and always have been nonsense, we know that. It's certainly the case that developers all over the place are being misallocated. But that's not unique to whatever we're calling "front-end" today. It's probably not even unique to software development.
