Can we remove the warning that swift interfaces require library evolution?

I'm working on a Swift dependency injection system that parses .swiftinterface files to gather information about the public types in modules, and uses this to generate Swift source code based on dependency requirements.

We're currently seeing this warning that swift interfaces require library evolution, though they seems to work fine without it enabled.

What is the rationale behind this warning? Could we remove it? Alternately, are there other, better ways to obtain this information? Thanks!
