Versioning the supergraph?

[forms-in-code]

Hi,

I think what I am trying to do is a bit unorthodox but ...
I would like to be able to version the supergraph such that when a new one is built we can send the version to our otlp system (datadog) and have that version show up in our APM. Currently it seems that the version of the router is being used to display the version.

For example if I have 2 subgraphs A and B and they are combined to make supergraph 1.0 when I change one of the subgraphs and create supergraph 1.1 I want 1.1 to be reflected as the version. The semantic versioning mechanism would be out of scope of this so from a router.yaml perspective it would be essentially a hardcoded value. From what I can tell there doesn't see to be a way to do this or send along any arbitrary information as part of the span ...
