Some things that need to be 'Implementation Defined' (like
representations) indeed can have a large space of possibilities, but
that isn't 'behavior'. Most cases of actual behavior the options are
relatively few options (perhaps making reference to an implementation
defined representation). For behaviors the biggest set I can think of is
the implementation defined value for assigning a larger value into a
smaller signed value, which technically is the choice of a mapping of
every possible larger value into a listing of the chosen smaller value,
but even in that form it is finite, and generally actually described as
a simple formula.

I do consider it a distinct category, maybe not a unique as between
Defined and Undefined, but with Implementation Defined behavior, I can
code based on that documentation an KNOW what will happen, and know that
it will be consistently that way. With unspecified behavior that is
impossible. Now, without access to that documentation, I can't really
utilize that advantage, so you can't write 'portable' code that takes
advantage of the behavior being implementation defined, but you can
write implementation dependent code that does. (One limitation is you
may or may not be able to put something in the code to confirm that you
are running on an implementation that matches the documentation you
depended on).

The fact that the options permitted by the standard can be organized into two groups, and it's convenient to describe each of those groups separately, doesn't change the fact that this matches the definition for "implementation-defined behavior".

Since the Standards committee hadn't thought of that wording, and since
some machines did trap on some values they couldn't specify an
implementation defined result, as that didn't fit, so rather than force
some machines to not be able to have efficient C implementations, they
left the result as simply undefined.
