Glow Lichen for Light in Hostile Mob Spawns

Hello,

I was looking for uses for the Glow Lichen as it seems to only be used for lighting and decoration. I thought it would be interesting if we could use it either natively or with crafting as a light source that allowed both players to see as per lighting, but not prevent mob spawns. Here are some reasons why I believe this would be beneficial:

• natural spawns for Glow Lichen could make areas where they are more dangerous while allowing players to see in caves since mobs could spawn in areas players perceive as safe.
• it would work well with Tinted glass in creating areas where mobs could spawn but players could see inside.
• give more interest to cave diving for a unique resource that players can look for and use.
• could be an interesting trade off with other light sources as lichen can be grown but doesn't stop spawning.
