Pretty simple, I think it would be nice to add RandomPlus (https://steamcommunity.com/sharedfiles/filedetails/?id=1434137894) to speed up rerolling for good colonists before starting the game, since it doesn't affect timing and the mod is only used in the "Choose Colonists" menu before the game starts. Of course, if this is allowed, it can always bring up future questions like "Why is this mod allowed and this one isn't?" or "Can we add this mod?"...

Not only the "Why this one and not ________", but it also opens the can of worms related to "what happens if the author decides to update this mod". If there is enough motion to suggest a change to the rules, it may be considered, but right now, the downsides outweigh the upsides.
