Requires 1 more reviewers from @axic, @g11tech, @Pandapip1, @SamWilsn, @xinbenlv

• Your abstract is a bit too terse. It should include a high-level technical description of how it solves the problem. In this case, maybe you could include a few sentences describing what it removes/adds compared to ERC-1155?
• The interface ID shouldn't be in the rationale section. It belongs in the Specification section.
• Same goes for the metadata extension. Since you're introducing new functionality, and not just explaining the reasoning behind your specification, it has to go in the specification section.

diff isn't showing bc i merged a different branch into main first, but recommended fixes are done

You have a "SHOULD NOT" and a "MAY" requirement in your rationale section. All requirements should be in the specification section.
