If I build a site with a feature module that includes permissions and then add a new role to my site, I'll need to recreate that feature to include the updated permissions for my new role? At that point, I've basically forked the original feature module for my own site.
Is it normal to have a feature module, such as a wysiwyg or blog, that is unique for each site? Are most feature modules that are available on d.o. (for example, the Debut modules) just a starting point to create a site-specific version for every site?
Is there a better way to handle this scenario? Do people use the same feature module across many sites?
