(b) Where functions do make attempts at being correctly rounded

correctly rounding.
I'm not sure that the complaints are about worst cases. More probably
software implementation vs hardware implementation in the average
case. But a new software implementation (better in average) could
help.
The complaints I typically see are about worst case performance. I
occasionally see requests for better performance with the potential loss
of accuracy.
