Logic if a field is not editable but required

Ok i got the following example.
I got a node with a title and a body. Bot fields are set to required.
I used field permissions to only allow admins to fill out the body.

So if a normal non admin user adds the node he only sees the title field, fills it out, hits save and then gets "the body field is required". He can not see it as he has no access to edit it but required is still checked. So shouldnt the required set to FALSE if a user is not able to edit/see a field?

I know that this module seems to chive that but in my opinion this should be included here because field permissions can not be used when a single field is set to required and not all users have access to edit it.
