True - I'd forgotten about that - and I have experienced the problem you've described. But, again in my experience, it's greatly dependent on the chainstay configuration. I.e. if the chainstay is dimpled and/or "massaged" in some manner, countersinking might not be necessary.

I suppose you simply have to be prepared for some surprises...
