Seems to work this way for me too, except that it should not. Or rather, I see 
no way how it can work for the following case:

exe a : a.cpp helper ;

lib helper : helper.cpp : <runtime-link>static ;
explicit helper ;

The 'a' target is not built for me, but I fail to understand why -- I never 
implement any mechanism to skip 'a' in this case and I don't see any new 
mechanism in your patch. I'd need to look at this in detail.
