The other use of drone cell foundation is to put in one frame into the brood box of your best colony in late spring.
Maximising the quality drones, to the benefit of mating queens eventual offspring.
For supers, it may be more important to get drone drawn on a closer spacing than 10/box, as the bees can be more 'free-form' with it.
Using it is a marginal refinement which most find no need to bother with.
Plastic foundation (available in Langstroth sizes only, I believe) isn't generally liked by beekeepers, or, it might seem, bees. However, commercial operators in the US may claim that there is a bottom-line $ advantage to them …
I'd have thought it's a lot easier to clean plastic frames to an acceptable standard then wood. Surely boiling them up/letting wax moths feast to get rid of the wax then a bath in Virkon S would leave them pretty much sterile?
If you boil plastic frames (or foundation), the reports are that it warps.
On the other hand if you are contemplating boiling, boiling wooden frames, briefly, in washing soda (no real need for caustic soda) does the job remarkably well.
