fun Request.formAsMap(): Map<String, List<String?>>

Why does this not return Map<String, List<String>> ? Why is the string nullable? 🤔

Because, like form Params, you don't even need an.empty string to pass. /foo?bar is valid

[dave]

Nullability is where a lot of http libraries fall down compared to the actual spec

[dave]

and don't get me started on WSGI in python libs ...

Ah, so /foo?bar will give "bar" = null, and /foo?bar= will give "bar" = ""?
