> When did designers become the gatekeepers in what a page should look like and how it should behave?

Since...forever? You may not like the waterfall model, but unless you're at a small startup this is how most software gets made. Even the more collaborative shops where FEs give input on designs, it's just that...input on designs owned by a designer. That AI leveled the playing field is my point. It's now much easier for designers to subsume the responsibilities of an FE than the reverse. You know this is true because if it weren't, designers would never have been a thing to begin with.
