There are pretty severe restrictions on the types of components that can appear in a SEQUENCE type.   It would seem unreasonable to impose those restrictions on the (private) components of C_PTR.   In practice, there is only one component in C_PTR, and it is an unsigned 64-bit address.  The limits on SEQUENCE types do not accommodate that sort of component. 


On a related issue, I'm not really sure why SEQUENCE is not already in the list of Obsolescent features. 

Cheers,
