cli Requesting data from a filename always yields Content-Type: application/json

According to https://httpie.org/doc#request-data-from-a-filename

It has the advantage that the Content-Type header is automatically set to the appropriate value based on the filename extension. For example, the following request sends the verbatim contents of that XML file with Content-Type: application/xml

I think it doesn't, because I always see application/json:

YAML Sample file:

test: true
foobar:
  - foo
  - bar

http --debug httpbin.org/post @example.yml

(Note the @ prefix)

Sorry, I confuse the < with the @ syntax. Still, when I use the latter I see the "wrong" content-type:

YAML is not a valid MIME type

Looks like CPython does not consider it a "common type" either (Source).

mimetypes.guess_type('example.yml', strict=False) will result in (None, None).
