They could be, and that's exactly what we'll do in Zig. But LLVM triples seems to be modeled on conventions in the C/C++ world, so I don't know how much appetite there is for introducing more components in the syntax - which you kind of have to do to avoid explosion when you consider libc vs platform ABI vs float ABI.
