I agree.  It is the ability of an application to define error codes which
it can later intercept - that is most important.

No.  9.3.5 clearly states:

    "A system choosing to execute THROW ... *shall* use the throw code listed ..."

It means, for example, a Standard system must use -17 THROW
... rather than  ABORT" numeric buffer overflow".

I see no point in a Standard mandating codes for exceptions which
it accepts not all systems can, or will choose, to handle.  Can you?
