I concur. But on the other hand, this granularity offers clear benefits,
provided that one can identify the low rates and heavy hitters. The usual
concerns related to tuning apply of course, as you noted. We'll see.

On a related note, it seems that there is some also ambiguity in the
standars with respect to pooled getConnecton() vs. getConnection(user, pw).
