Looks like a lot of these includes don't need to be in the header.

Scrubbed here and elsewhere (referred to lint output).

do you need to own profile here? It looks like profile is a global obj.

The profile handling looks a bit more interesting.  I use a function that Clank
uses in some cases, but this function is marked "avoid using at all cost".  I
think I need to rework this.
