You're of course right. This is for the immediately "containing
function", not for the "current stack". But 'this-command' could do
the trick;
diff --git a/lisp/view.el b/lisp/view.el
index 204e28c2a2..2a0fc85cb8 100644
--- a/lisp/view.el
+++ b/lisp/view.el

When I have this, and view-read-only set to t, C-x C-f'ing to /etc/fstab
gets me the message but this:
(run-with-timer 1 nil (lambda () (find-file "/etc/fstab")))
does not.
Anyway, feel free to beat me to the patches to jsonrpc.el and Eglot (the
former you can do directly on the tree, the latter can be done via
GitHub, or just send me the patch here).
