Global "include in map" flag?

[stingray300k]

Right now, the logic for inclusion in the map is:

• all mesh-type objects that don't have mesh_as="NONE" (or MODEL because that's not implemented yet)
• even those meshes that do have mesh_as="NONE" if they have an entity classname or entity key-value pairs set
• objects of any other type if they have an entity classname or entity key-value pairs set

Perhaps it would be better if, in addition to that, there was a global "include in map" flag at the top of the BlendRadiant properties for easily switching "off" certain objects without having to change any of their properties?
