That's what I thought would be the case and have done but it seems
that rpm with the auto deps still wants the dependency for the root
package as well.

For example with a package I maintain called geoclue I have two
subpackages called geoclue-gypsy and geoclue-gpsd to try and keep the
deps down (gypsy and gpsd essentially do the same thing) but if you
just install geoclue without any of the sub packages it will still
pull in both gpsd and gypsy as deps. This is what I want to avoid. A
yum output eg below.

Cheers,
Peter
