bug#68687: [PATCH v2] Use text/org media type

[Max Nikulin]

I am sending an updated version of the patch, earlier I missed one 
occurrence of text/org.

I am leaving it up to you the decision concerning mailcap.el.

I do not mind. I just do not see real reasons to do so taking into 
account applicaion/vnd.lotus-organizer in Emacs and text/org in XDG.

Likely it is not. It is documented in man pages for various tools. In 
Emacs-27 mailcap.el was severely broken, so I do not expect detailed 
documentation.

It has happened so that I has spent some time reading Python bug tracker 
concerning their mimetypes module. I suggest against doing it 
unconditionally. Give users controls what sources should be used and 
what priority each source should have (application internal mapping, 
system-wide configuration files, user configuration files, Windows 
registry, XDG files as possible future improvement). Inconsistencies are 
not uncommon, updates of the IANA registry are applied with different pace.

An alternative is to negotiate with maintainers of mime.types in RedHat 
and Debian. My first impression is that in the case of Debian it may 
take enough time before any reaction. I am unsure as well that IANA will 
agree to change media type for .org without approval from IBM.
