This is true, and why I also filed bugs asking for a robust reflection and dynamic method compilation. Thankfully, they were duplicates.

But not all of the cases can be accomplished using these techniques, and even those that can, it's often more code.

The ability to reason about which methods are getting called at runtime has been a powerful tool since the beginning of iOS development, and in Mac and NeXTStep development before that. It would be a shame to lose it.
