To be clear (as there is already some confusion in the short thread) -

Commenting out the radios on my sketch is all that is required to have locally attached sensors working, correct?

The first response have a bit of a rabbit hole of data which delt with v1.5. Just want to make sure 2.0 fixes all of that.

I've been looking for a definitive answer on the forums and the site but cannot find anything that mentions it.

I'm trying to set up a simple single door sensor with an ESP8266 12E. I will use the ESP as a WiFi/Ethernet gateway. Do I need to connect a radio too? What purpose would the radio serve in that case (seems to be a serial bridge for other 'nodes' in the system, right?). If I don't need one, can I simple not #define MY_RADIO_XX? Will the sketch work as normal?
