1) Because it was already separated into msvc.default-path rule. You can 
add more rules to msvc.jam if you need more modularity.

2) msvc-config is an experimental thing. msvc toolkit should have its 
own autodetection facilities. It's not a good idea to deprecate

using msvc : 8.0 ;

We need using msvc ; syntax to work. We need a consistency between toolsets.

I'd like detection using environment removed completely. Can you imagine 
a scenario in which registry autodetection will fail?

I think environment detection is only present because there was no way 
to access registry in early BJam versions. Can someone confirm this?
