We work with complex entities in a Symfony2 - Propel environment. Most of the time we need to include some scheme-definitions from vendor-packages. A little problem there, adding the external module results in the scheme being editable.
I think it would be a nice feature to make an entire Skipper Module read-only. This feature then should not allow editing a region, nor exporting to the scheme file.
PS. This setting should be save on project level, not in module.xml
