Tunnelling everything through post is the normal way to do e.g. rpc over http. It’s not a soap thing, it’s also how xml-rpc, json-rpc, and graphql work. More generally it’s how you layer over http when you can’t necessarily guarantee respecting its requirements like purity, idempotence, or cacheability (or don’t want to bother), or when you fear hitting it’s practical implementation limits.
