It's possible, but you'd need a way to turn it off. It would be better
to add %i interpretation to the semantic consumer of the value, probably
/lib/svc/method/test-fmri in this case.

This is because your manifest has the data property_group element inside
the service element, not the instance element. Therefore svccfg import
created the property group on the service. This command tries to set
the property in the property group on the instance (test-fmri:porta),
but the property group doesn't exist.
svccfg -s test-fmri setprop data/port="/dev/porta"
or
svccfg -s test-fmri:porta addpg data application
svccfg -s test-fmri:porta setprop data/port="/dev/porta"
should work.

When you create an instance, it doesn't have any property groups. You
must add the property group before you can set any properties in it.

That should work. (Note that it's svc.startd which expands the %i, not
svcprop or svccfg.)

Indeed, svccfg doesn't know anything about property composition, but
svcprop uses composition by default. This is because svccfg is meant to
provide access to the bare metal of the repository, but unfortunately
right now it is also the only supported way to set properties.
