I don't think lib.php is always guaranteed to be loaded, I think this needs to be inside a callback such tool_heartbeat_after_config but this only landed in 3.8. We might not need older support, if we do there are other callbacks we can use

can this be conditional so if it's not configured we don't add the wrapper

I don't think we should check that config is in a certain state here, it is normal that you might not want to use this and it shouldn't be a warning.

It isn't very clear what all the lines from here to line 80 are doing. All of the $statcallbacks stuff seems very complicated, I believe it is all to allow injection for the unit tests? Is so could this just be tucked away into a getter?

I would like to avoid exceptions where we are adding instrumentation to a page and now the page has the possibility of failing due to the instrumentation. I think a debugging() call is a better option here

I'm not sure that $PAGE is always setup. Will comment in the wr we might want something else here
This is suboptimal, the same call may have already been made in request_shutdown()
