Reading the recent Visa press release: Why would the real world asset issuer ever use an interoperability service not owned by them? 

Isn’t this just introducing more trust assumptions to their product?

Said another way,

bankA uses Visa tokenization platform to put 10B of tokenA on Solana, Ethereum, and privateChain.

Why would tokenA adopt one of the existing or emerging standards for interop vs using Visa’s attestation service to mint/burn tokenA across chains?

Great point, also in a world where the attestation service tries to rent/extract the alternative rails provide a way for users to avoid that fee

This is where composability comes in handy, devs don't need Visa approval to build a wrapped version of its off-chain secured tokens.
Anyone can deposit those tokes into a nice interoperable factory and get fungibility of assets on all the other chains Visa won't natively support.
