That is a great question. Some background on the issue. This will be TLDR for most but...
Around 1993 the ACBL legalized Multi for some of its higher level events. Unfortunately, at that time, the powers that be decided it was a good idea to introduce a requirement for suggested defenses. At first, this was something the players were supposed to provide.
An an early event under those rules, I was playing Multi. My opponents had agreed to use our suggested defense. However, when it came up, they didn't look at it, because they had a hand they wanted to make a 'natural' takeout double of diamonds!. We got a poor result, and appealed.
The committee said our defense was too complex, so we lost.
The next step was the committee decided to write their own suggested defenses; Multi users were required to provide these defenses. As an aside the defense we suggested became known as the 'simple defense'. Delicious irony.
Things were still quite restrictive. The books created an air of difficulty to most players. However, Multi was still allowed at all open NABC events and top level regional events.
The next step in the process was the elimination of Multi for 'pair games', since the suggested defenses do slow the game down. (They also create oodles of Unauthorized Information).
This was the state of affairs when I joined the Competition and Convention committee, the body that makes suggestions to the BoD about such issues. This was the Spring of 2015.
One of the major reasons I joined was to try to get the Convention charts updated. I was appointed chair of the subcommittee for this in the Spring of 2016. We had a very forward thinking group. We wanted to reintroduce Multi to NABC pair events, plus the Reisinger. We also wanted to slowly phase out the defenses, which we felt might destigmatize the dreaded Multi.
However, we didn't even get past the C&C level. There was a strong sentiment to keep the suggested defenses, and to keep status quo. A straw poll of the bridge committee of the board saw a unanimous vote for keeping the defenses wherever Multi was allowed.
Also, at about the same time, the ACBLs influence on the WBF convinced them that allowing a written defense to Multi was a good idea. At least there, you need to bring your own defense.
That brings us to today. While we still allow Multi in some events, the future is not bright for any progress in that regard. We were successful in making the charts much more liberal than they were, although there are still other areas where ACBL is Big Brother.
