Sounds good - but I have a bit of a concern that this will then behave differently from other APIs. 
While our use of warning (non-failure) UErrorCode codes for default/fallback results has turned out 
to not be a good idea, it's pretty consistent.

In other words, you should currently get a default-warning code which passes U_SUCCESS() and is only 
reasonably reliable if you preset the error code precisely to U_ZERO_ERROR. (Warnings are not 
cleared out automatically.)

This is fragile, but standard - and the proposal fixes it but makes it non-standard - so I don't 
really know what to recommend.

What does everyone else think?
