How do you define "almost total lack"?  Just to pick two examples,
the Sun Ada native compiler for SPARC has by my count 16 implementation-
defined pragmas and three implementation-defined attributes, while the
DDC-I cross compiler for MIL-STD-1750A has 13 implementation-defined
pragmas and one implementation-defined attribute.  (By comparison,
DEC Ada has 26 implementation-defined pragmas and five implementation-
defined attributes, although the pragma total is somewhat inflated by 
having different EXPORT and IMPORT pragmas for different language entities,
rather than "overloading" them.) 

Are there specific pragma- or attribute-based capabilities that you 
expected Ada compilers to have, that have never materialised?
