I agree, but since Ihor indicates that is impossible for now, we will
have to live with the current situation for at least the near future.
So I think we should install these changes, but please audit them
carefully to make sure we don't create any backward-compatibility
problems unnecessarily. For example:

I'm not sure the removal of text/x-org in these two hunks is a good
idea: could it perhaps cause trouble to someone, e.g. if an email
message is sent from Emacs with this change and read by Emacs without
it? (I don't use these packages, so I wouldn't know the answer.) In
general, I'd prefer changes that add text/org without removing support
for text/x-org.
Thanks.
