I don't know if this is a good example, but if you look at StackOverflow,
it seems that people who want to see a list of constraints appear regularly.

Given the questioner restricted their question to “for a given table” I’d say it supports leaving the status quo, not changing it.
If, as you suppose, these come up regularly then finding one that asks for it “in the entire database”, ideally with some stated goal, should be doable.
