I tried advising eglot--format-markup to bind view-inhibit-help-message,
which gets rid of the most annoying messages, but some still seem to
emanate from jsonrpc, which calls read-only-mode in
jsonrpc-events-buffer and initialize-instance.  I'd rather not have to
rely on advising internal functions, but maybe I can't have my cake and
eat it, too.  ;)
