Are these new fieldtypes robust enough to replace those?
UPDATE: I think I might have been too general/vague in my description. To clear things up, these are 3 features that I need that I am not sure is doable in Relationship/Grid
- A radio button that is a "is_default" field. This means that it should be aware of the other radio buttons in other rows in that there should only be one checked radio button at all times
- Pagination support for Grid
- Multiple relationships field inside Grid. I am aware that the new Relationship fieldtype supports multiple relationships now but the question is if it is available inside Grid
