I agree both that that could be done and it would be a bad idea. But I
given up the pursuit of checkmarks unless the particular feature has
merit. After many long years of experience, I eventually figured out
that checkmarks are usually counted to justify a decision already made,
and straining to to justify a dubious checkmark rarely effects the
outcome, and if the extremely rare case that it does, results in an
unhappy customer. I'd rather put time and effort into features that we
think important and useful and leave the Oracle pseudo-emulation to
somebody else.
