I'm curious about the "environmentally friendly" promise. How meaningful/measurable would removing these tags be?

I think there's something to be said for efficiency/no wasted bytes, but better for the environment feels like a major stretch/beside the point...

It's like saying "if we all cut out unnecessary adjectives from our speech, it would save 100k gallons of water per day." Could that be true, maybe? But that's not the thing that makes brevity meaningful/important.

(or: Tongue-in-cheek joke that went over my <head>?)
