You’ve described the reasons why aliens that see in the radio spectrum would never evolve in the first place. Aliens from a particularly cool star might have their vision attuned to infrared, but no place that’s warm enough to have liquid water would be cold enough to make radio waves more useful than infrared.
Yeah and even functional infrared eyes need to be at least twice the size of ours if not over ten times for more far thermal ranges. Anime eyes. The classic 20/20 D&D infravision would require eyes the size of basketballs, lol. Dark elves would put the innsmouth look to shame.
