Custom functions are not implemented in generated files, so there is no reason to include headers for their types. We already have this behavior for their argument types.
This is a minor roadblock for WebCrypto, where I have custom functions that return promises, but no matching headers for promise types. And a desirable behavior in any case, I think.
