What's a "private installation?" An installation "for this user only?"

IMO we can cancel any auto configuration we want, since there is
always manual configuration. It may not make sense to support the
complexity of two autodetection mechanisms.

It isn't?? IIUC even non-default VS installations set the registry. The
installer gives you the option to *not* set up the environment, so I'd
think the registry would be the more reliable of the two.
