The equivalent for NURBS is more about doing a similar process on your original curves to smooth them out or simplify them and recalculating the loft or sweep, rather than working on the NURBS surface directly.

But one thing that can make this difficult is if you're trying to do a "reverse engineering" type task where you're trying to very specifically control the curves to match some existing blueprint. That has a tendency to lead you to put in more points or more curves, it can kind of lead you away from a simple curve setup...

Yeah for those things you use the "even more traditional" and fundamental NURBS tools such as extrusions, revolves, and booleans which are pretty much immune to buckling or wiggling type problems.
