Guix QA review form submission:

Updated the description accordingly

No, the package doesn't depend on rust-mode at all. It shells out the cargo
and rustc instead. The require calls in the elisp files are

(require 'xref)
(require 'compile)
(require 'button)
(require 'markdown-mode)
(require 'tramp)

Of those, only emacs-markdown-mode is not a built-in package. Although we
could add xref and tramp as inputs. They are also distributed as separate
packages in GNU Elpa. This means they have a separate release cadence from
emacs. What do you think?

Thanks, it is true 'hackers count from 0'. ^_^. Updated.

Cheers
