It's plausible that someone could use that much power, but not "line of site" of their spotter.... ;-P They come in a variety of powers just like any other Vtx. 200mw for example https://www.readymaderc.com/products/details/1258-1280mhz-mini-200mw-transmitter And again, even if they were running 2watts, they would not stomp on any other band.Then this is an error on my part as most of the 900mhz stuff (albeit very few as I have little interest in long range) was being flown with power levels in the 1 to 2 watt range from ground stations. Granted this was over 4 years ago before the 5 inch invasion started.
