I work at a large ISP now, and you're absolutely right.  You don't just go 
around resetting interface counters on backbone routers for the hell of it, 
and we never do it without customer permission while troubleshooting an 
issue with a connection, that is why I said I thought it was a non-argument.
There seems to be an irrational fear of counter-based anarchy here.

I've already said I'd drop the issue 4+ days ago, and that I'd be more
than happy to do it in userland as you suggested, my point was simply that
adding it to only one userland tool will lead to inconsistencies.  It is not
an issue of being able to "work perl" or not.
