I maintain that when we implement this API we should differentiate between
integer and double prefs. Just because JavaScript only has the "number" type
doesn't mean the distinction doesn't matter. Case in point: we have setURLPref
but in JS a URL is just a string.

This gives us two benefits: the API can create the correct Value subtype for
calling PrefService::Set, and the UI can do sanity checks or even inferences
("if the type is integer, limit the slider to integers").
