I'm not sure I'd call "how Lanefan actually runs his game" or "how a few others have /do run their game" an "experiment".well, the experiment was under 1E rules, so all those minimums applied. I suppose it was good that it was just an experiment and not some DM who insisted on '3d6 in order'.....
The section of the rules you are referring to as "bad" RAW was mitigated by the presence of alternative attribute generation methods, I posted options five earlier. The "problem" goes away if some of the various options were used & goes back to the question of why you feel obligated to force a gm to accept a style of your choosing after accepting the initial "use x" & not getting the result you wanted.The point isn't that the DM is enforcing the RAW, it is that the RAW itself was bad. It is an arbitrary restriction that adds nothing to the fun and is personally nonsensical, but DMs will use it just because it's RAW. Which is why the RAW has to change. A Good DM should probably look at the situation and make an exception since it harms little and increases fun and goodwill. A lesser DM will enforce it because it's the Rules and try to justify not only its inclusion but its necessity.
It's only modern d&d with a set of rules (both RAW & effectively RAI) that tries to "force" one particular style. Modern d&d does that by omitting all other options & emptying the gm's toolbox in favor of a "rulings not rules" shaped IoU.
