Organic Groups: Non Domain group nodes in og_actions (and views exposed filters)

Hi,
Using domain access with og works quite well. But there are some places where it does not:

• 
  Actions like "add post/member to group" show all groups.
• 
  Views exposed filter OG:Filter by OG shows all groups

I solved the views problem long time ago by creating a custom filter. I never cared about the actions, now I do. I found out its the og_all_groups_options() function in og.module that does the group node loading. So I made a patch for og.mocule to hack the domain logic into it. What do you think about this solution. As far as I tested, I had no side effects.
