No, it isn't, it's controlled by

Why ?? This hasn't been the case for at least two decades of
Solaris and beyond.
Probably an oversight, I'd guess. As with many such situations, things
that
aren't obviously and critically broken don't get much attention ;)
It is not really an oversight since all computers with a TCP/IP stack
need to deal with some level of routing even if they are not acting as a
gateway. If there is ever more than one way to get "there" via the L2
network then running a higher-level routing protocol (e.g. RIP) can help
the TCP/IP stack make the right decisions if the involved routers use
the same protocol. The host might participate in RIP or it might just
act as an observer.
In many cases one or more computers are attached to a shared L2 network
with a single upstream router. In this case, using DHCP to configure the
default route, or static configuration to provide the default route, can
be a good choice. There are other means such as ICMP Router Discovery
Protocol (https://en.wikipedia.org/wiki/ICMP_Router_Discovery_Protocol)
or even ICMP redirects.
I have a few machines with two L2 networks (a.k.a. tagged VPN), and even
those don't require the routing service. In fact, in my over 3 decades
of experience with Sun machines, I only once have seen that the routing
service had to be active. That one case was when I experimented with the
COMSTAR network simulation tools to play with virtual switches and
routers.
Goodness, what a lot of mails!
This is indeed a bug:
14006 ipv4-routing should not be enabled by default
https://www.illumos.org/issues/14006
I haven't had time to work on it, but I am happy to talk it through
with people who would like to pick it up and get it fixed!
In principle, the easiest fix is to revert to
<instance name='default' enabled='false' >
in the respective services in /lib/svc/manifest/network/routing/ .
But I've not seen a 202* OI version, I'm still on 2017...
