It doesn't solve the problem that anything needed for the build target has
to be listed in Build-Depends instead of Build-Depends-Indep, so these
packages need to be downloaded/installed unless you start hand-hacking
around this in the package or in the build tools.[1]  But then again,
there's no metadata to tell you which build-dependencies you can ignore when
you're not building docs, so you get to do this by trial and error, which
rather neutralizes the intended time-saving benefits.

Whereas Build-Depends-Indep was always intended to be used for precisely
this, and only the "build-arch" detection problem prevents it being used
this way.
