Not necessarily. There's always the option to port something like LineageOS yourself, which is in fact where most of the ROMs for a much larger selection of devices comes from than what is officially supported by LineageOS. This is of course not for the average user, but it is possible. Except for some devices like the newest Samsung flagships that are based on Snapdragon. With the Exynos variants, porting AOSP and operating systems based on it is possible.
I don't understand. There's a large list of officially supported devices and users can create support for even more devices. Doesn't that mean that there is a wide range of phones that support custom ROMs, even if not all phones are supported?
