I couldn't find any discussion in regard to this specific issue, but looking at

http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#6

it seems that they would prefer to see a paper before the committee would
perform any further action. It seems that inline functions are possibly less
controversial and

http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#1049

addresses a similar problem in regard to inline functions with reference
parameters.
