A multi game is IMHO a serious thing. The question is what do we (or you) want ? Many many multi games with the same validation process as for CoC and puzzle or a limited amount of multi games validated using a much more robust process in order to guarantee their quality ?
The actual validation process has shown its limits a long time ago on CoC. The validation process is more a click rush than a valid review process. This lead us to reject subjects which probably can adapted to real valid subject but are not valid in their current state just to prevent their validation in their current state by people who just click validate because they found (or not) a solution (possibly hardcoded). This phenomenon has migrated recently on puzzles even if its less visible at this time and I predict it will appear soon on multis.
An other drawback of the multiplication of multis will probably be that people won’t even try to solve them. Bender - Episode 4 has 17 participant, Vindinium 135, BitRunner 147, Cultis War 34 … The community has not enough time to fight on all those multis.
At this time, as far as I know, all the gurus have stopped to play CoC (at least with their official account). Many have stop to solve puzzle. I think it will be a pity if the also stop to play on multi.
Allowing the community to participate by proposing ideas and code is IMHO a good idea. Allowing us to participate to the validation process also. Allowing us to validate using the same invalid process as for CoC is not.
But maybe, CG has an other official vision.
