I think you're right that it's a personal customisation and it's not
really org's job to defend against it. I don't think the major mode hook
should be disabled, as there'll be other things that users might want to
configure, and retain in org-edit-src and htmlized versions. Do you
think it would be of sufficient general utility to add hooks to org to
cover this? (in which, e.g., outline-major-mode could be turned off?).
I.e. something like

1. org-edit-src-mode-hook *
2. org-export-preprocess-src-buffer-hook

Or maybe those should be the same hook?

Dan

* Btw, a trivial thing, but I wonder if it would be appropriate to rename
org-exit-edit-mode as something like org-edit-src-mode; it now has two
keybindings only one of which is to do with exiting.
