What are your doubts exactly?

Shader precompilation is a standard thing to do now - consoles mostly ship precompiled shaders for their GPU + driver combo, Steam Deck will also download precompiled shader for its Linux + AMD + driver version combo.

The infrastructure for that Steam side is there and is in active use.

Well my doubts are that the feature is actually working. Im not saying that precompiling shader doesnt exist neither it cant be done. But based on my comment, i doubt it working the way as described. Else i would not have to recompile those shaders every time for every game in my library.
