Exactly -- that's precisely the functionality that sub-packages is going
to introduce for the ports. You do one build stage, and can then split
up the results into several different packages. One port, several pkgs.
This will require the use of a staging directory, so you can package up
a port without having to have it installed. Staging is another new
feature currently on the drawing board.

Well, maybe. For an end-user system where you install from pkgs (in
this case, meaning pkgng -- that's the driver for most of these new
features ) you only really need the base 'foo-0.99' package:
dependencies will be pretty much equivalent to what there is now.
Optionall you'll probably want foo--docs and foo--examples too, but you
don't have to have them if installing a really stripped down system.
There will probably be some sort of global setting to say automatically
install docs and/or examples when you install the primary port.
When you're doing pkg building, then yes, you'ld need to install a bunch
more pkgs -- they'd be BUILD_DEPENDS rather than RUN_DEPENDS -- but the
ports infrastructure should take care of that. Using a package builder
like poudriere to maintain your own pkg repo should become standard
procedure for supporting any reasonably sized installation, and that
will gloss over all the boring detail of that for you.
Cheers,
Matthew
