I believe at the very least they could offer a more flexible way of managing Service Quotas.

Currently it's too much of a hassle to increase/decrease account-wide limits: it takes too much time, depends on AWS Support, UX is nowhere as nice as, say instance reservations etc.

As a result of this people tend to increase the limits once in a while just to make sure it doesn't become an issue at a very unfortunate time, and that's it. It never gets decreased/managed again. It's obviously not seen as a use-case by AWS, since they only have a "Request quota increase" button in the UI, and no "decrease" button. [1]

SQ on its own wouldn't cover all kinds of costs (for on-demand items like Lambda executions they offer limits on rates, not total count), but it'd be better than nothing, it'd prevent scenarios where you'd wake up to 100 GPU instances mining bitcoin, and it's within the quotas since Bob asked for an increase two years ago to try something.

[1] Just having a button there would still be an awful UX, yet I believe its complete omission is noteworthy.
