You mean the module interface is immutable to macros defined in the
importing translation unit? Yes, allowing this would be pure lunacy.

The following will still be possible, right?

#import foo // Exports macro FOO.

#ifdef FOO
# import bar
#endif

Or even this:

#import FOO

This will require the back-and-forth between the build system and the
compiler I mentioned earlier.
