Shutup Experimental Settings! Mod

Shutup Experimental Settings! is a mod that removes a screen in Minecraft that warns you about using experimental settings.

In Minecraft, starting around the 1.16 era, the Experimental Settings screen was introduced into Minecraft. The experimental settings screen mostly came up if you had a world with custom world gen, custom dimensions, or other unsupported settings. There is also a warning symbol next to the worlds with these experimental settings.

This screen normally does not do anything, and if you press the button saying you know what you are doing, you won't likely see the screen until you apply new experimental settings. The initial screen, though, is just seen as an annoyance for some people. In some laggy modpacks it becomes very unpleasant, if not impossible, to click that, especially in a server setting.

Shutup Experimental Settings! removes this screen. When creating a world with unsupported settings, Minecraft will skip this screen. This does not mean that this mod may fix the issues that come with experimental settings. Broken world generation, broken biomes, and most notably, broken datapacks (which still can prevent the world from loading even with the smallest errors) still exist and will not be fixed with this mod and still need to be fixed by the mod/datapack author. This mod does the same thing as pressing the proceed button. The dragons they talk about in the warning messages may still be there, and like other modded content, you will not get support from Mojang.

The mod is very lightweight, with an empty entrypoint and a simple SpongeMixin specifying the lifecycle as stable.

There are a lot of similar mods which do the same or similar things. One of the most notable ones is Disable Custom Worlds Advice for Fabric and Quilt, which is what Shutup Experimental Settings! is based on (and which supports Shutup Experimental Settings! And is listed as a co-author of it) and is for Fabric but does not require Fabric API, making it suitable for cases which you do not want Fabric API.

Shutup Experimental Settings! is a good option for modpacks since it is very easy to put in. It's an excellent option for people who just do not like the experimental screen or just want to make worlds a lot or make worlds and walk away while the world is made, or for people playing a laggy configuration and pressing the button is a pain.
