Would this not work?

(:if exists {$Group}.GroupHeader :)
(:include {$Group}.GroupHeader :)
(:else:)
(:include Site.DefaultGroupHeader :)
(:endif:)

Well, I believe that the objective is to suppress the
GroupHeader on a specific page in a group but allowing
the GroupHeader to be included in the other pages of
the group.

I was not suggesting that the directives not continue
to be based on core implementations unless this truly
was a goal to eliminate them.

While the directive may no longer work as a
suppressor, certainly similar pagevariable base
solutions could achieve this, couldn't they?

(:if expr exists {$Group}.GroupHeader && equal
{$:nogroupheader} :)
(:include {$Group}.GroupHeader :)
(:elseif equal {$:nogroupheader} :)
(:include Site.DefaultGroupHeader :)
(:endif:)

Simply set nogroupheader to something within a page to
suppress the group header inclusions on that page:

 (:nogroupheader:true:)

This seems like it would be possible for Site.Header
also if you don't want to implement a separate
(:nositeheader:)
