I meant `wid-edit' doesn't even check whether it's a "directory name" in
the sense of a filename ending with a slash (`wid-edit' doesn't
discriminate directories and files although it provides separate widgets
for them).

Agreed.

What about `call-process-region', `start-process', `shell-command'?
Maybe we could introduce a macro like
(defmacro with-valid-default-directory (&rest body)
"Run BODY with `default-directory' bound to an existing directory."
(declare (indent 0) (debug t))
`(let ((default-directory
(if (and (stringp default-directory)
(file-directory-p default-directory))
default-directory
(expand-file-name "~/"))))
,@body))
