Advertise client version in the identify exchange

[dennis-tra]

Describe the solution you'd like

It would be great if nimbus could announce proper version information in the identify exchange. We @probe-lab provide metrics on client version distributions here: https://probelab.io/ethereum/discv5/2025-22/#agent_semvers_over_7d_plot-plot

However, nimbus clients only report the string: nimbus while other client implementations give more information about the version, os, architecture, commit hash, etc. in the string. A few examples:

• Lighthouse/v7.0.1-999b045/x86_64-linux
• Prysm/v6.0.2/b4a66a09933007af2ff25a8970daaaf810896038
• teku/teku/v25.4.1/linux-x86_64/-eclipseadoptium-openjdk64bitservervm-java-21

Would it be possible for nimbus to adapt a similar pattern?

We're not likely to do this.

What's the rationale? Is there a discussion somewhere that you can point me to?

One of the reasons why we are not revealing client version is:
