I found a relevant commit from 2018 by Lars, and its commit says:

src/process.c (connect_network_socket): When an async :family
'local client fails (with a file error, for instance), mark the
process as failed.

https://github.com/emacs-mirror/emacs/commit/92ba34d89ac4f5b5bbb818e1c39a3cc12a405790#diff-18c8f6291e2c6a6f88223e509421492528e624157da1ba063401a6ffc36e63b6L3595

Does failed here mean the Qfailed status? Then why is status set to
to the car of file error returned by get_file_errno_data  which
returns file-error or some other file related bug?

Somebody who was part of this discussion then may be able to shed
some light on it.
