For me it’s the notification light you used to find on older phones, was particularly good to know if your phone was charged without picking it up

It’s not strictly there as a separate feature. Modern radio chips in phones are universal programmable radios, they can catch and process any wavelengths if you install correct code into them and plug a correct antenna. The same radio chip processes your 5G, Bluetooth, WiFi and everything else.
What phones are missing are FM antennas and radio firmware with FM support. This FM support is a paid feature for phone makers, so they don’t add it.
