OG wiki posts and nodeaccess?

When I have nodeaccess enabled, Organic Groups wiki posts cannot be edited by all group members anymore.

I am running OG Version 5.x-7.3.

Here's what I wanna do: Whoever is a member of an Organic Group has to be able to edit all posts inside of it. There are other users, who are not members of the Group and who may be granted update rights to single nodes within a group. Theoretically this could be done with OG wiki post types and nodeaccess for certain content types. However, the wiki post functionality is lost with activation of nodeaccess module. Is there anything that can be done about that or do I just have to live with it?
