At least in the IBM COBOL's I've worked on, it's not likely at all.
The IBM language reference for enterprise COBOL says it's permissible
to omit both the INVALID KEY and ERROR/EXCEPTION procedure. As you
say, this is probably an extension to the standard to remain
consistent with older IBM compilers.

In any case, it's the programmers responsibility to determine that the
file operation was successful and take appropriate action. If they
don't, it's the old "results are unpredictable". I would assume that
the program would simply continue.
