I appreciate looking at things from a different perspective! I can see your line of argument now.

I should clarify. I don't think JS killed frames, that's not what I meant. If anything, I think JS could have saved frames. But the failure of frames left a gap that eventually JS (esp. with AJAX) filled. Lots of other stuff was going on at this time too, including alternative tech like Java, Flash, and ActiveX, all of which were trying to do more by bypassing the "standard" tech stack entirely.

I think the ossification of web standards from ca. 1999 to 2012, combined with the rapidly growing user base, and with web developers/designers aggressively pushing the envelope of what the tech could do, put the standard stuff on the back foot pretty badly. Really, I'm talking about the whole ecosystem and not just the standards bodies themselves; there was an era where e.g. improving HTML itself was just not the active mentality. Both inside and outside of W3C (etc.), it seemed that nobody cared to make the standard stuff better. W3C focused on unproductive tangents; web devs focused on non-standard tech or "not the intended use" (like tables for layout).

So I think we can say that <frameset> frames died a somewhat unfair death, caused partly by their initial shortcomings, partly by people trying to break outside of the (literal) boxes they imposed, and partly by the inability of the standard tech to evolve and address those shortcomings in a timely fashion. But just as there was a reason they failed, there was a reason they existed too.
