I definitely agree that not being able to capture "UI/UX shouldn't suck" in a formal requirement is a problem. Developers have to be vigilant, or get a lot of help from QA (typically the latter).

In my experience, though, there is a bit of a feedback loop during government test events since those are often staffed by real end users. If the end user doesn't like the software they can just say it failed the test, even if it did meet the requirements as written. So at least there's a bit of an upside there.

It would be nice if that feedback with the end user could occur earlier in the process though.
