Is HDMI CEC really in demand

HDMI CEC is used by very few users. For example, you mostly watch cable TV, having set up HDMI CEC you can turn on the game console with the TV, but you turned on the TV to watch the news, it is inconvenient to turn off HDMI CEC every time in the settings. With the advent of Internet television, the use of HDMI CEC becomes unclaimed.
But if for example you watch satellite TV, then of course you have configured HDMI CEC, when you turn on the TV, the satellite receiver will turn on, this is certainly convenient.
