I am wondering if there is a pure-wayland-client version of emacs, as discussed here[1]
A debian emacs-nox appears to exist [2]

On my system, apt show emacs-nox tells me
--8<---------------cut here---------------start------------->8---
Description: GNU Emacs editor (without GUI support)
 GNU Emacs is the extensible self-documenting text editor.  This
 package contains a version of Emacs compiled without support for X,
 and provides only a text terminal interface.
--8<---------------cut here---------------end--------------->8---

IIUC, wayland gets input events like keystrokes from the kernel and sends them by
registered call-backs to the programs that thus registered interest.

But I wonder how this connects with emacs and its use of pts/ptmx, readline, etc ...
Is there a legacy layer of vt encoding/decoding that could be eliminated by a more
direct use of wayland protocol?

Perhaps such an emacs package could have a smaller closure,
by depending as simply as possible on wayland (sans Xwayland)?

If the low level stuff were wrapped nicely in some guile extension modules,
I suspect other uses than emacs would be found.
