Even as a someone who is something of a UI/UXtist myself, I found it pretty awkward to navigate to the right place to submit feedback. I don't want a "Ask Question" button, I want a "Submit feedback that will probably never be read by anybody important" button.
Typing this I noticed a similar feedback post from 2014, so I guess it's one of those old familiar "eh" suggestions that might get addressed after everything else. Which is fair.
A simple change to lessen confusion a bit would be to conditionally alter the button text from "Ask Question" to "Submit Request" when the requests tab is selected. The next low-effort change could be to add a few buttons here and there on all SE sites that link to meta.stackexchange.com/?tab=requests.
