Well, if you want to go down that road, discussing this could reach a
Suggesting a different implemention is better taken to Yum
Basically, groups are just lists of packages, with additional attributes
for the packages (such as "mandatory", "default", "optional") to subdivide
them helpfully. A groupinstall is used to install a list of packages,
a groupremove is used to remove the same list of packages.

IMO, that's a matter of definition. If you find "ppp" on your system, and
assuming  it is part of two groups, how to tell whether it was installed
due to installing group G1 or G2? And if "ppp" were not required by anything
else, why would it be wrong to remove it as part of G1 without specifying G2?
I mean, you asked to remove the packages from group G1, why imply that you
want to keep some of them due to another group they're in? Btw, you would see
the same dependencies when running plain "yum remove ppp" or "rpm --erase ppp".
 "ppp" isn't part of two groups, is it?

You could raise that question on the Electronic Lab's list:
It could be that they consider these font packages worthwhile for their
spin, but without making any or all of the apps depend on all these
font packages. Along the same line, I could use Emacs with the fonts
as installed by the default Fedora Desktop spin, but I add xorg-x11-fonts-misc
nevertheless for the config files I use.
