I'm sorry, I couldn't quite hear you— perhaps more all-caps would help? :-)
The dogmatic 'swap is bad for performance' is justified only because
writing/reading a slow disk is bad for performance.

flexibility in how it manages all of the available temporary space.
It's something that people who are very concerned with swap impact on
performance should appreciate greatly.
