Tally is a community-owned, open-source fork of MetaMask. From first impressions it looks like it will also solve some of the issues brought up in Moxie's (excellent) blog post, i.e decentralizing the node-> NFT->wallet Metadata routes.
Regarding the immutability of NFT image pointers:
Some emerging solutions to this issue are:
Use ERC2477 (DRAFT). This allows you to have some control over the metadata to ensure the name is as you want it. Note that this will require you to implement a zero-knowledge proof or a JSON parser on-chain which validates the new metadata.
Use 0xcert Framework. The 0xcert framework is specifically designed to provide metadata integrity for ERC-721 tokens, it uses a different hashing technique (Merkle tree). But it requires you to use the same schema across metadata versions.
Ceramic Network is doing some interesting work on schema coordination amongst other things.
