You mean that a package installed in the global zone won't be inherited into
the non-global zones? If so, I think it is not a big problem. The user can
always install the packages individually into each zone. I think that is
better anyway because (1) the global zone can be minimized, (2) each
individual zone can be minimized, (3) IPS packages can be managed
independently in each zone. The disadvantage is that the sharing features of
zones would not be exploited. IF the user wants Zones + IPS + sharing then
they will need to wait for a release of IPS that fixes that bug. But, there
are a lot of cases where that isn't necessary.

If ZFS de-duplication were to be implemented then a lot of the motivation
for inheriting packages from the global zone goes away--you would just
install packages into each zone and the common (parts of) files would
automatically be shared between all zones. Then non-global zones would only
(have to) inherit the very few packages that must not differ from the global
zone.
