[sv-bc] question about specify blocks

The specify blocks have not been enhanced to take advantage of the new
datatypes. For example the
syntax only allows scalar, vector or bit select, part select range
expression in the path specifications.
Is this a known specification hole? Are we expecting to fix this in the
future and specify timing on various 
packed struct members and perhaps even unpacked datatypes?
 
I realize that we could specify timing on packed structs and packed arrays
by determining the part select
corresponding to the member of the struct or sub-element of the packed
arrays, but it would be a lot more
readable to be able to use member selects and multiple indices.
