This seems like a terrible reason to choose the architecture of how it’s implemented in LLVM.  The clang driver is part of the LLVM project.  If we need to add support for some kind of special SPIR-V flag akin to -emit-llvm, we can do that.  If a particular frontend vendor wants to customize the flags, they can always do so themselves.
