With the proposed expansion to include ERC721.the title should change.

I regularly wish I had got token level metadata included in ERC721: EIP 821: Distinguishable Assets Registry (Contract for NFTs) · Issue #821 · ethereum/EIPs · GitHub

That would be a great EIP. Go ahead and write it!

Is there any statistics on how many ERC20 token are using this ERC1046?
Considering the major ones, I am not sure it got any adoption traction.

Also advising not using name() goes against the autowrapping multichain protocols like xERC20.

I would also like to know how widely erc-1046 is adopted. Is it a problem that meta data behind the url could be changed silently? Moreover recommending not to implement erc-20 data fields (name, symbol, …) is actually breaking the erc-20 interface.
