It's unlikely there will ever be official support unless Sphax wakes up one day and decides to work on it, but I doubt he wants to due to the following stuff...
Ultimately too many users have issues with Bedrock even without fancy, badly implemented features like Ray Tracing. Nvidia abandoned their own pack which was meant to be the big "oooooo, look at what ray tracing / shaders can do" because Bedrock is just so poorly optimized.
We've also recently found out that no one at Mojang is working on optimization fixes for resourcepacks anyway, so version to version, as they add more stuff it's likely to get worse. It doesn't seem to bother them that there is an issue about lag with HD packs on their bug tracker that has been open for nearly 2 years.
So with all that in mind, and with us having to manage 3 resourcepacks for 2 versions of the game (that even today still are generally treated separately by Mojang), we just don't have the time or drive to work on Ray Tracing / Shader support.
That being said, if someone wants to support the feature themselves and release it in the Mod Patches section, they can (as long as they don't include any unmodified textures from the base pack).
