> it's a shame you need mods to have shaders on Java

You don't. Ever since 1.17 you have been able to build GL shaders directly into resource packs. Resource packs don't require any complex loaders and don't pose a malware risk. To install them you can either drag-and-drop them as .zips directly into the resource pack menu, or a server/world can be configured to prompt the installation of a resource pack. These resource pack shaders are not quite as flexible as Aperture, Iris, or Optifine shaders, but they are fairly close in functionality.

I'm curious if they will carry over this functionality for Vulkan shaders embedded into resource packs. I suspect they may not, which is understandable given how it can be used to break the game's functionality much worse than an ordinary resource pack can (not full RCE, though)
