    > One approach (which this PR tries to follow) is to expose basic values which can
be sampled by a more sophisticated monitoring tool. Average, sliding window, etc. can be implemented
in there.
    
    That's fine, but I guess my thought was that sampling in this context will have very low
fidelity vs having the server calculate, the avg for example. Given the monitoring tool will
poll every 5 seconds or so (perhaps less frequently) the number of samples vs the number of
proposals could be very low. Not a reason not to do it, but I'm not sure you're really going
to get what you expect as an operator.
