The problem with this is the problem we have with hasFeature. At what
point do you declare that you support the feature? As Schepers said,
if you support 4/5 mouse events, do you support the mouse events

The UA already makes a declaration of support at the property-value
level. And it's specific enough that in most cases you can answer
"is this property-value combination supported enough to be usable".

(Note: usable != bugfree)
