Selecting a profile should never be destructive. Maybe I just want to 
load new handlers or run a single import step.

But why not clearing the registries if a complete base profile is 
*applied*? Even if it is the current base profile I can't see why we 
would not want to do that.

I don't want to go down that road. The next step would be to keep track 
of the applied profiles a snapshot is based on. Things become more and 
more complicated and we still can't rely on that information: Sites 
created with older CMF versions don't have that information and manual 
customizations can make it quite useless.
