It would so nice if the fabric api provided a specific banner pattern api, of which we can add custom patterns without the need of going through the risks of ASMs. And i know abt the impossibilty of having extensible enums in general, but isnt there a specific way to make custom banner patterns easily doable?

Banner patterns can now be added using a registry:

Identifier id = new Identifier("mymod", "pattern");
Registry.register(Registries.BANNER_PATTERN, id, new BannerPattern(id.toString()));

is there any guide to how to use it?

FabLabs has Banner++, which hopefully will become part of Fabric API eventually.

Oh that's nice! So it is confirmed?

It's under debate, and we're gonna see if it gets merged in. For now, just use Banner++ directly.
