Why should we disable the rounding heuristic?

Shouldn't instead the callback be called after an integer solution is
found by the rounding heuristic to verify if the new
integer solution is valid?

This is definitely a choice, but requires a bigger change to the callback API and additional effort in callback development. Therefore I still think that the option to disable the rounding heuristic (as well as every other heuristic) should be available.
