I suppose one can only ignore the difference between NAD83 and WGS84 for so long...
For years, I have used Carlson Survey (2016 with IntelliCAD 8.1) to import and export kml to/from Google Earth. In Drawing Setup I can sepcify Lat/Lon Datum as NAD83 or WGS84. But if I use my own LDP, it forces me to use WGS84, and if I use SPC, it forces me to use NAD83. As far as I can tell, Carlson actually exports the kml as NAD83 regardless of the setting. It has always matched the GE imagery fine, so I didn't care. I can often pick well-defined points off of GE and get coordinates that match surveyed NAD83 coordinates within a foot.
I think that means that the GE imagery is actually referenced to NAD83, not WGS84. That is, until Google updated the photo earlier this year. The new photo is shifted about 4' NW of the old photo (2013) and it matches (within a foot or so) the kml exported from J-Field. So it looks like Google's new photo is on WGS84 and Carlson has a bug to fix.
