I think I agree with you here, unless "bjam -q" is explicitly requested. In 
that case I'd like everything to stop.

I'm not so sure. In the general case I'd prefer error messages being output 
and a summary error status returned from bjam. Still not saying everything 
should stop though.

I realize that when by default building a large set of variants, such as 
when invoking "bjam install" from boost root, the <build>no feature would be 
very nice to use.

OTOH, what should happen if someone requested e.g. 
bjam --toolset=msvc --threading=single --runtime-link=shared from boost 
root? For this case it should definitely not silently generate nothing, 
IMHO.
