Early in this thread, I pointed out the interesting language of the GCC.
GCC said:
ONE CLUB OR ONE DIAMOND may be used as an all-purpose opening bid (artificial or natural) promising a minimum of 10 high-card points.
I wondered if this meant that only one of them could be used. The other might have to be natural or more likely, artificial and strong. After all, the ACBL could just have easily written...

Just now I found where this very concern was being discussed.

I'll include the text at the end of this post.
People can interpret OR as...
1. one but not both
2. and/or
So we have another ambiguous GCC statement.
Apparently, two different TDs gave two different opinions on whether it should be the one meaning or the other. Richard Beye, the Chief TD, had the opinion that the rule means "either" or "both". If so, then it seems even more likely that one can assign more meaning to "all-purpose" than some have thought.
I think many of us (at least myself) have thought of "all-purpose" as a catchall bid which is somewhat necessary if playing a strong club and even more necessary if playing a strong club with a 5-card major system.
If we can have 2 all purpose bids and neither of them is designated strong, then it wouldn't make sense to have 2 catchall bids...at least not 2 catchall bids showing the same set of hand-types.
I had argued for 1D as four spades predicated on other legal openings denying four spades. My argument was that 1D didn't "show" spades so much as "infer" spades.
I can't say "1C is my stuck bid for hands that don't qualify for 1D, 1H, 1S, etc. bids" while simultaneously saying "1D is my stuck bid for hands that don't qualify for 1C, 1H, 1S, etc. bids" I have to give meaning to one before the other can become a stuck bid.
If I have 2 "all-purpose" bids, it seems reasonable that I ought to be able to organize them such that both have meaning. If my openings (yes, no strong bid)are now...
1C-four hearts
1D-four spades
1H-five hearts
1S-five spades
1N-balanced, no major
2C-clubs
2D-diamonds
it would be disingenuous to say that my 1D "infers" spades. No, it unapologetically "shows" spades.
Perhaps the ACBL had envisioned something instead like...
1C-promises a 4-card major
1D-denies a 4-card major
Perhaps they didn't. Anyway, I feel more comfortable assigning meaning to 1C and 1D, and I have the email from the ACBL (which I posted earlier) as confirmation.
Here's the text from the link I found...
The quoted ACBL General Conditions of Contest regulation is ambiguous.
> Grattan is interpreting the meaning of the word "or" as the logical
operator
> Exclusive Or - with an implicit "not both" in the GCC.
> Others have been interpreting the meaning of the word "or" as the
logical operator
> Inclusive Or - with an implicit "and/or" in the GCC.
I noticed the same thing and asked 'rulings@acbl.org' about it. Notice
the effect, though, if you think the rule means "but not both." If that
were so, whether a particular 1C agreement is legal would depend not
only on which hands are shown by the 1C bid but also on which hands
might bid 1D on an entirely different deal. Such a rule would be hard
to enforce, to say the least. In fact, Richard Beye, the ACBL's Chief
Tournament Director, confirms that the rule means "either or both."
However, this confirmation came only after a different TD had given me
the opposite answer! So Richard Hill's basic point, that the rule needs
to be written unambiguously, is confirmed.
