Pro: You don't need server infrastructure to customise a Shopify flow.
Con: You need coders knowledgeable in WASM.
However, I could imagine that an ecosystem of "plugins" could emerge, i.e. ready-made WASM apps that merchants could plug into their stores.
There might be more security issues though, if the developer of the WASM and the merchant using it aren't the same party. I think it will be interesting to see how this will play out.
Then again, it might be sufficient to to code something in an LLVM-supported language of choice, then compile it to WASM and just hook it into Shopify, without needing to understand the WASM code that was generated. Good luck troubleshooting or debugging this though...
