Please declare these new scheme-specific header argument in
`org-babel-header-args:scheme'.
See `org-babel-header-args:C' for an example.
This is necessary for header argument completion to work.

Also, please document the new header argument in the ob-scheme
documentation at
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-scheme.html
(you can submit a patch against
https://git.sr.ht/~bzg/worg/tree/master/item/org-contrib/babel/languages/ob-doc-scheme.org
 )

This does not look right. Your change will disable session support
completely when host and port are not provided.
