Don't know about rationale (might be compatibility issue with Ada 83).
I use files mostly directly or as instantiated generics encapsulated
inside other classes (which may be derived from limited controlled) to
do automatic cleanup when needed.  Those are pretty much like C
FILEs.  I have issues with Root_Stream_Type being not controlled
type.  That seems to be bigger drawback.
