The answer to this question is simple. There's feature <toolset>, there's 
subfeature version of <toolset>msvc, but the "feature" module does not 
support default values for subfeatures. So, when you run "bjam" the build 
request contains only

<toolset>msvc

and nothing about version. BTW, a desire of default values for subfeatures is 
mentioned in comment on line 131 of msvc.jam --- though for a little bit 
different reason.
