I have mixed feelings on it. GNOME Nightlight only exists because a number of people complained that the lack of screen-temperature API made Redshift on Wayland impossible. On the one-hand, the feature is incredibly useful, and great to have it included in all GNOME installs. On the other hand, this is exactly what Google and Apple did when they kicked apps like f.lux out of the appstore, and then rolled out their own built-in blue-light blockers. If your end goal is making the feature available to as many people as possible, then great. But from the perspective of a small developer, however, "OS vendor forbade my software on their platform, then ripped it off and baked their own version into the OS" leaves something of a bad taste in my mouth.
