I think that niche standards such as 1788 have a limited opportunity to alter
  the computing environment.  I expect 1788 to be visible in the development
and distribution of standards-conforming software libraries.  If EDP is
such a valuable tool for such libraries, implementers should include it as
an internal component for those routines that benefit from it.
 Perhaps it should be made visible as an API to library users.  As far
as I can see, it  would not fit neatly into conventional programming languages.

Richard:

the problem how to include the  EDP into conventional programming languages has been solved more than 25 years ago. See the literature listed below. ACRITH-XSC is a Fortran-77 exrension for the S/370 architecture. [4] describes among others how the EDP is implemented on the S/370 architecture.
You may find some of the literature in your library.
