This suggestion is pretty close to what we are working on. I agree
with you that only one source package is needed, but with more than
one 'build-stage' (as opposed to multiple source packages).
Using a virtual architecture of 'bootstrap' to annotate the build-deps
is neat. It deals with the issue of repeating the build-deps in
Buildd-depends-StageN as sugested in the URLs below. However it does
limit you to only one 'build stage'. i.e there is the normal build and
there is the bootstrap build. You cannot have 3 stages of build. This
may not be a significant limitation, but we need to be fairly sure of
that before building it into the system. Cross-toolchains packages are
one thing that does have more than just bootstrap/full. How many
others are there, and how do we deal with them?

Which I referenced earlier in this thread, and have expanded upon, here:
http://wiki.debian.org/DebianBootstrap
I'll add aba's option to that.
