also, i have the same question as tony. if nwam already supports
profiles why is this case even needed? why doesn't install just apply a

The reason NWAM can't be used is that NWAM has a different notion of
static addresses than what we provide for enterprise servers using
network/physical:default.
NWAM's notion of static is reactive in the sense that the static
configuration is not applied if the link isn't up (cable plugged in),
whereas the network/physical:default applies the configuration whether
or not the link is up.
Thus replacing network/physical:default with a static NWAM profile would
introduce a new failure mode; if the cable is unplugged the server can
no longer talk it itself, and server applications that bind to the local
IP addresses of the system would fail - since the addresses wouldn't be
configured when the link is down.
Hence we can't use NWAM for this right now.
Thanks for that explanation, that makes a lot more sense as the reason
why NWAM can't be used than wither or not the NWAM configuration of a
static profile is in an SMF xml fragment or not.
One of the many projects underway in this area is to consolidate NWAM
and physical:default. The NWAM engineers are involved in this and other
network configuration projects.
That helps too.
