In Grian's Video he explains how Glass should break quicker than stone, considering that glass is fragile, yet Mojang made mining glass slower than mining stone when having haste 2 from a beacon.
In this simple datapack, I changed so that you can break it with any tool you want and will break almost instantly. Will work with both haste or Efficiency.

NOTE This is a very simple and small datapack. I believe it would work from 1.14 to the last version of minecraft. I haven't tested it on them yet but if it doesn't, let me know.
