Yep - See some of the work my last team published here while we were rebuilding deployment tooling: https://blog.coinbase.com/scaling-developer-productivity-d23.... For hard to measure metrics, softer measurements like repeated team surveys work fine too.
I'd be cautious of directly measuring "assistance" outside of peer input in perf to avoid an unhealthy incentive. The most helpful people I've worked with in the past tend to grow through strong peer reviews and having the most opportunities to join new projects.
The OP here really misses the point of demonstrating impact. Doing the right thing ethically then for the business is a strategy that is, well, rarely the wrong thing. Optimizing just for getting promoted might is a greedy strategy that might get you promoted once, but good luck finding peers that want to work with you again.
