Yep, now shader writers only need to test for and work around backend bugs in drivers. Also it makes gamedevs slightly happier that they don't have to ship the plain text source code of their shaders with games. It doesn't provide any real security against RE, as SPIR-V is pretty close to being tokinized/SSAed GLSL and decompilers are trivial to implement. But if it makes them happier, so be it.
