SPIR-V is a lot more like minified JavaScript or JVM bytecode than it is like x86 code, at least. In some cases the games' shaders haven't had any optimisation done and you can more or less fully reconstruct the original GLSL, albeit without comments or identifiers. Also a lot of textual shaders were already unreadable generated code. But for the ones that weren't, it's definitely a loss for those of us trying to peak at the internals of games, indeed :)
