Based on my experience, this isn't actually a problem for people interested in trying it with their TV as RF remotes included with STBs, streaming sticks, etc., still have IR transmitters built in to control the TV.
Specifically, the actual device (e.g. cable box) is controlled with RF signals (often bluetooth) but the power and volume buttons are often controlled via IR because those are functions of the TV and most TVs have IR receivers. TV power/volume can also be conttolled via HDMI-CEC in theory, but in practice I've run into compatibility issues more often than not that way whereas doing it over IR just works.
