Before this all headed off into the weeds, it *was* a topic looking for more info on WiFi based timing enhancements. We still do not seem to have any real input on that side of it.
Hopefully somebody will pipe in at some point with real info on what the WiFI chipset guys are trying to do. At some point I would think it’s got to be made public ….

The little interfaces that you put on a Arduino and such expose a serial port kind of interface with a AT command set. I think they bury most all of the stuff we'd want to know about.
