Not with any existing mechanism in WebKit, unfortunately. This is blocked on <rdar://problem/37710976>.

This should probably be in a HAVE(MOBILE_WIFI) #ifdef.

Also, it's a bit confusing that taking the assertion puts things in "background' type, and releasing it makes it normal.

Agreed. I had to double-check that those are the right types to use. Strangely enough they are.
