I would be hesitant to go there as well!

I have been rereading your proposal, and I think bullet 2 and 3 (section "one
possible design") might be just enough, ie give enough hints. (Bullet 2:
"[...] header [...] processed ahead of any dependent headers [...]"; bullet 3:
"[...] when processed [...] removed [...] and replaced with [...] has happened
[...]".)
