I think that the sources-subvars target must function without any
Build-Depends-(Indep) installed because otherwise:
- Checking out the source from RCS or downloading the source leaves the
source without full Build-Depends.
- Without Build-Depends the source can not be build.
- Without build the sources-subvars can't be generated.
and you are stuck in a vicious circle.
Similar for a debian/control target in debian/rules. Although there you
at least have the old Build-Depends to get you started.
Overall I'm not sure the substvars would be better than a debian/control
