This is the need Nr. 1 that I/we have indeed. The separation of single and collection fields has too many drawbacks, actually I don’t see any benefit it at all.
Basically, what is most useful is custom entity view layouts in which fields can be drag dropped in any location the use likes, regardless of the field type.
