I'd like to give it a try to look into Serving internals a bit more. /assign dsimansk
/cc @taragu BTW, this is also one of the ways you can improve GSD, if we extend the activator reporting capabilities (not necessarily a good idea, but something to consider).
The rest of this is not a good first issue anymore and requires a fair bit of caution. I'm happy to help people through it, but it's much more involved. Also kinda blocked on #8377 to refactor the scraper in a way to make controlling it's lifetime more predictable.
This issue is stale because it has been open for 90 days with no

If there are no ready activators but ready pod endpoints requests will bypass the activator even if TBC=-1

Kindly to ask if this issue still open?If is, I’m glad to try.

When the activator is in the routing path, scraping the pods is kinda useless as their information is effectively zeroed out, because all requests are considered "proxied", thus the activator metrics take precedence. We can use that to make our system more efficient in these cases!
I propose two steps to go about this:
As the PodAutoscaler owns all of these decisions, this should be doable for us. As it's a good-first-issue, I'd love to see it land in two separate pieces as laid out though.
Note: I'm happy to mentor first-time contributors here. The changes needed should be fairly small in terms of number of files to touch.
