Pascal. It contains handle, a buffer, and function pointers for the main
routines of the Pascal stdio. (so that different files can have different
handlers)

Short answer: Because dos is pretty much dead.
Better answer: unreal only helps from the view of a single program. If you
have multiple programs, where do you put the second it so that it has the
same advantages as the first? (iow always load at the same address, linear
access to all ram in one continuous block)
Keep in mind that unreal is just a hack to simplify protected mode. In
32-bit protected mode, the application has a full address space for itself
in thoery.

Nearly any swag like initiative would be good. But to find, select and
categorise large amounts of snippets that really add to swag is a lot of
work. And the numbers of programmers DOS are somewhat in decline compared to
SWAG days.
