Allow players the option to use the old school light system

For those of us without graphics cards (which are REALLY hard to get and also EXPENSIVE!!!) playing bedrock edition on pc feels a bit lack luster without the shaders we once had. I personally came from pocket edition to pc and was excited for an upgrade in the shaders I could run on my laptop, but now I cant. Can we get the option for bedrock players to have the old light system back and be able to use custom shaders? The render dragon is supposed to be an upgrade but it instead has barred many of us from having shaders at all. It feels really weird to have such a limit on the customization of this game out of all of them it would be really nice to get that back! Please and thank you  <3
