Why aren't there more glow in the dark keyboards for a more passive form of keyboard backlighting? (leminal.space)

Is it because the glow would fade after a year or two? Even if it's not cost effective compared to adding to LEDs I thought it would be a novelty thing.

I did a quick search online and it doesn't seem very common. Mostly keyboard covers.

This is the same principle behind phosphorescent rocks. UV light "excites" them, and for a time, they release that energy as visible light (luminescence). When they calm down again, incognito.
