No, because, where shield designs differ by agency for the same logical
network classification, the network tag does not change, despite the
differing shields.

One of many examples: Maryland uses a unique green-on-white shield for
US Business routes, but those roads still get tagged as
"network=US:US:Business", not "network=US:US:Business:MD" or somesuch.
The renderer would have to detect which agency the road is "in", and
render the agency-specific shield accordingly.
