Err, let's keep using examples to avoid miscommunication :p If I understand
you correctly, you mean this:

root:
... images:
........ image-a
........ image-b
... assemblies:
........ assembly-a
........ assembly-b

When running from root, you can use:

> mvn <goal> -pl !root,!images,!assemblies -N

This will build image-a, image-b, assembly-a, assembly-b. It skips all
three aggregators.

By the way, -pl !xxx,yyy is still perfectly possible.
