No. Clip groups retain edits, fades, and clip gain, but don't do automation, plug-ins, etc. For that you need track import, and we're back to Frank's original post.
Clip groups have been super-useful to me with recurring bits of complex sound-design that are heard in multiple episodes. Also useful for stacking splits of recurring musical cues in music editing. For all those workflows, I actually prefer not having plug-in info.
