Any particular reason GsonSerializer.read casts deserialized json to Any ? And not Any? ?

[spand]

I know it is not valid json to send a naked null but most support it regardless

[spand]

Including Gson itself

[bdawg.io]

Why isn't null valid JSON?? It's valid in RFC 8259 (Dec. 2017) and RFC 7159 (Mar. 2014)

[bdawg.io]

A JSON text is a sequence of tokens. The set of tokens includes six structural characters, strings, numbers, and three literal names.

A JSON text is a serialized value. Note that certain previous specifications of JSON constrained a JSON text to be an object or an array.

...

A JSON value MUST be an object, array, number, or string, or one of the following three literal names:

false null true

See sections 2 and 3
https://tools.ietf.org/html/rfc8259#section-2

Note that certain previous specifications of JSON constrained a JSON text to be an object or an
   array.

A bug it is then !
