Comment (by dd32):

 > I understand. But we do use can in many places, and don't use should
 yet.
 It looks like the only place we use `should` is in the Background Update
 methods. It looks like all other things are mostly `can` as they test the
 ability to (or a setting), followed by filters.

 > We should be explicit, always.
 We actively discourage being explicit when not needed. We do not use `if (
 false === func() )` unless it's needed, we encourage `if ( ! func() )`
 instead.
