I believe this is the wrong question. For a new feature, the question should be 
"why should it be included", not "why shouldn't it be included."

For example, UDAs in general are not actually necessary. They can be faked using 
a naming convention, and such is very common. The trouble, though, is that if 
one uses UDAs a lot, then the complexity of the naming convention becomes 
unbearable.

It's become clear to me that UDAs can be used a lot, and so more targeted 
support for them is justified - i.e. a compelling use case.

It's hard to see that on parameters, though.
