But which custom macros, exactly? If your macros expand to private APIs 
usage, we can break that anytime we want.

Exactly, but this is unsupported right now, so we can do a SIC. (If it's 
behind a opt-in / opt-out mechanism, even better).

Hopefully we can detect it (e.g. GCC/Clang define __EXCEPTIONS when 
exceptions are enabled), and make our macros return instead of throw, 
i.e. keep the current behaviour and the current limitation of being used 
only directly from a testcase function.
