I can't see the point personally, who's going to choose the packages?
Plus that's not even getting into the technical difficulties of plugins going wrong, what if one or two plugins in a given package stop working together after a few updates, whose resposibility is it then to fix the package, and what action would be taken, the package removed, adjusted or the effected plugins removed from that package?
By all means if someone wants to start a site that offers or recommends plugins as packages they can do so, but for me i don't feel such a thing would work for this site.
That's my opinion of course, others may have different thoughts or feelings about it..
Additionally you may wish to post this to the ideas section.
