Well...a combination of lucky & smart.
1. With electro-frog you recognized the need to provide insulated rail joiners at the diverging frog rails and permanently wired power for other track extensions. Good move.
2. But with a brand new switch you don't yet see a need to have the point rails and metal frog powered through extra rail feeders and a separate external switch. So far you have good connections to power those rails. Just wait until the points get dirty and internal connections start to corrode.
3. Without derailments you have not yet seen what happens when you get a wheel to opposite polarity point rail short while the point rail is being powered through the tiny contact area of the opposite point from a 5 or 8 amp booster. As soon as you burn the points good once or twice, re-read #2.

4. With insul-frog you don't need the insulated track joiners at diverging frog rails as those rails don't switch polarity. The frog itself is insulated. But now you have a known dead spot in the track. Usually works OK with all-wheel pick-up on diesels.
5. You can still have something similar to problem #3 above as connections to the inner turnout rails are bonded together be metal to metal contacts in the plastic molds rather than good solid soldered connections. Eventually you will wish you had added more rail feeder drops.

You don't HAVE TO do anything to these switches to run trains with DCC (except recognize the need for #1 above). Your luck and annoyance level may vary. Making them more DCC Friendly simply reduces the probable occurance of occasional annoying problems that takes the fun out of running trains when they keep stalling at track switches.
