OK. Your point is:
  In most cases, the binary stanzas in debian/control will contain the
  correct set of binary dependencies at the beginning of the build.
With which I agree, of course.

My point is:
  There's nothing mandatory about having the binary stanzas in
  debian/control contain correct information at the beginning of the
  build.
