It seems like it is written now as something that is required for every execution. I don't think this is necessarily a bad thing, I just wonder if it would be beneficial at all to make it optional to allow for executions that don't utilize a TG to just not specify it.

If there's a legitimate use case (or we can imagine one) for this in
CI (or anywhere else), then we'd want to make a TG node optional.
Let's leave the implementation as is and make the TG node optional
once we discuss it further in the CI call. We talked about a mechanism
to skip test cases based on the testbed capabilities and I think this
would fit into that (as TG could be viewed as a testbed capability).
