sys-fs/udev uses the uucp group for linux dialout devices. This is the standard group for these in gentoo. We have a bug open to base-system to determine whether we want to replace that group with dialout or continue editing our rules. By creating the dialout group on your own, you are creating an unnecessary divergance for our users. Now people will not only have to add themselves to the uucp group to use these devices, but to the dialout group if they install systemd.
There is a thread in gentoo-user mailing list currently where VirtualBox doesn't work w/ systemd because it uses the dialout group, instead of uucp group. Should use uucp until bug 454556 is resolved, after it's resolved, we can convert everything from uucp to dialout, but not before, so systemd is really doing something unwanted here at this time.

Any suggestions for how we would resolve this for current installs? I assume we would want to remove the dialup group somehow. Or can we can just leave that for whatever conversion happens in baselayout?

I think we are stuck with uucp group because of http://bugs.gentoo.org/show_bug.cgi?id=454556#c3 I'm not sure if we are ever going to change the group in Gentoo then :-/
It was decided long time ago in bug 108249 that the uucp group should be used for this purpose. Please stick with this, and don't create any new confusion.
