I can think of advantages of having it as a command line option, though:
If a new runtime emerges, it does not need to patch clang, but instead it can use the -f switches. And it also means if a runtime gains a new feature, it does not need to patch clang. I can understand that you don't want to have a long list of options that are required in order to work with the runtime, so I have another proposal:

What about introducing a new -fobjc-runtime-features=foo,bar,baz with an alias for already known runtimes?

For example, you could specify -fobjc-runtime-features=direct-class-refs,non-fragile-abi. But as an alias for these two, you could also specify -fobjc-runtime-features=gnustep-1.0.

Any comments on this?
