I haven't. The current behavior of merging query and form params is done by one of the middleware biff includes IIRC--muuntaja I think? It would probably be worth thinking about whether even that is a good thing--e.g. should people explicitly destructure query-params + form-params + path-params separately? or merge them all into one? I guess it wouldn't hurt probably to have params be the combination of everything and then people can decide whether to use it or not. in short: I haven't thought about it at all up until now, but I'm open to it. I'd just want to spend a little hammock time before merging it into Biff.

Muuntaja just handles the body-params, so something else. Reitit coercion middleware push the coerced parameters under :parameters with submaps for :query, :path, :header, :body etc. If you are interested in using those, I could pair up to integrate those in.

Thanks, good to know! I'll take a look at that sometime
