[Request] Fix Physics

[MelvinMod]

General Information

i have viaforge-mc189-4.3.2.jar and EndeavourOS

Request

I want you to make a selected version (for example 1.21.11) convert physics (even stairs that not let me go on some servers) to 1.8.9, yes and you can just make a setting to enable new physics or disable new physics (keep 1.8.9 physics), it will looks like teleporting but pls, made it, also you can enable old PVP from 1.8.9 on new versions (yes, it's like a cheats, but it's actually good feature)

and it's good to see some settings for this mod, because 1.8.9 is the best version that works better with ViaForge and i played whole my life 1.8.9 and never played newer versions

and fixing a physics of you/me (who is playing) by modifying server for those who using ViaForge, not for others
