My man page for svc.startd(1M) as shipped with Solaris 10 doesn't
have any such section.
For what it's worth, this is the sub-section titled "Logs":
Logs
By default, svc.startd provides logging of significant res-
tarter actions for the service as well as method standard
output and standard error file descriptors to
/var/svc/log/service:instance.log. The level of restarter
action logging is specified by the options/logging property.
As you'll note, this mentions standard output (stdout) and standard
error (stderr). This is not the same as what I'm referring to and
that is capturing text sent (directly) to the console. I'm fully
aware that it captures stdout and stderr already. Some applications,
be they daemons or otherwise, do output to the console and not
stdout/stderr.

I'm well aware of this and it is of no bearing to the problem
or the suggestion/request.
Would you rather try and piece together the output saved
in 100 or more different log files or have it all in one?
