Why is it that no one writes with portability in mind in druntime?

Having 80-bit reals on platforms that support them are helpful for 
numerical simulations.  There use to be an article about this decision. 
 However, phobos should never use real for this reason.  It should only 
be used by application developers.   Maybe a compiler flag to error 
when compiling code that includes real to make sure portable libraries 
don't use it?
