I very much agree with that. It makes sense to use them only for big repos and big repos usually don't pass a 20% threshold very often.

I would agree if split index was the default mode or if our goal was to eventually make it the default mode.

Or it could be a new "mixed" mode for core.splitIndex (which might eventually become the default mode) to have no split-index as long as the repo stays under a lower limit and to automatically use split-index when the repo gets over the limit.
