With the addition of lower CS values like CS0, the current rule prevents mappers from using the entire grid in maps.
The current rule states:
However, having objects slightly off-screen does not create reading difficulties. I believe the main issue is slider bodies/tails obscured in such a way that reading them is non-trivial (I use this idea in my Chouzetsu Yokoku).
Proposal 1 (this enables mappers to use off-screen readability as a mapping technique):
The current rule states:
Hit objects must never be off-screen in 4:3 aspect ratios. Hit objects that are even partially off-screen can create reading difficulties. Test play your beatmap to confirm this.This prevents low CS mappers from using the bottom-most part of the grid like x:0 y:384. Example: beatmapsets/1296266#osu/2689496

Proposal 1 (this enables mappers to use off-screen readability as a mapping technique):
Hit objects must be playable in 4:3 aspect ratios. Hit objects may be partially off-screen as a mapping technique, but should be readable relative to the current difficulty.Proposal 2 (this prevents off-screen readability as a mapping technique but enables low CS maps to use the entire grid):
Hit objects must never be off-screen in 4:3 aspect ratios. Hit objects that are not off-screen when the circle size is 3 are exempt from this rule.
