Perhaps not accurate, but if one removes eg version 2.0, then I wonder if anything will run anymore

>That's not quite accurate. 2.0 is an upgrade to 1.1 and actually changes some of the assemblies. Some namespaces/classes/etc are replaced with new ones. 3.0 and 3.5 do not touch the core 2.0 assemblies, but rather add additional assemblies. So, updating 1.1 and 2.0 doesn't do anything to the 3.0 or 3.5 versions.
