delay-mode-hooks is now in emacs-27.

I don't know how to handle this more properly because some hooks
should be run with buffer-file-name, e.g. generic-mode-find-file-hook
that uses buffer-file-name to add more font-lock highlighting.
But some hooks like in Eglot assume that buffer-file-name associates the
buffer with a file.
Also I tried to use indirect buffers:
(let ((buffer (make-indirect-buffer
(current-buffer)
(generate-new-buffer-name (buffer-name)))))
(funcall
(unwind-protect
(with-current-buffer buffer
(let ((buffer-file-name "/tmp/foo.el"))
(set-auto-mode)
major-mode))
(kill-buffer buffer))))
but not sure if it's enough to just set its deduced mode.
