I see the problem and I stumbled upon it also, but I don't like the solution.

My proposal: extend the syntax for ds_pointerField.

The new syntax is 'type1:subtype1[,type2:subtype2 ...]'. Within the 
flexform the key is type:subtype with an excpetion for the first type. 
Subtypes of the very first type can be set in the data structure without 
the type (to be compatible).

If a type has no subtypes the subtype part may be empty in ds_pointerField. 
In the DS it has to be 'type:' or mabe 'type:*'.

Such "magic first elements" are already there in other parts of the TCA, 
where you have <table>_<id> lists but may leave out the <table>_ for the 
first table of the list of allowed tables.
