The problems are technical.

It is for the ObjC++ maintainers to produce patches that do not adversely 
affect the memory consumption, compile time performance or maintainability 
of the C or C++ front ends.  These are technical issues.  If existing 
slots in datastructures are to be reused, then all uses of those 
datastructures in the existing front ends need analysing to make sure this 
is safe (probably with checking added to the accessors to ensure it 
remains safe).  If new slots are added, statistics of performance on real 
code are needed to show no statistically significant adverse effect.  
Similarly, if conditionals are added anywhere someone thinks might be a 
hot spot, profiling results are needed to show there is no performance 
impact.
