I am not subscribed to mailing lists due to lots of trafic going on there, so I
am not overly introduced in directions in which org goes, so forgive me if I am
not so familiar with the latest features.

Well, yes something like that; make features available outside of org-mode, and
make org-mode use those features instead of having everything in a monolithical
library.

The idea was that if such a minor mode has a list of regexes it recognizes,
neither org-, md- or hyperbole would need to keep their code for this, but could
relly on users to just (desc-links-mode +1). If I had this as global minor mode,
I could also enable it while writing mail and use say md syntax and have pretty
links, which admittedly would come out ugly on the other end, but that is an
agreement between the reader and the writer. In other words org links or md
links would be available in any format and up to users where they want to use them.

Not a novelty at all :). The same as for links. A user could (rich-text-mode
+1), and have org-markup (or their own) available in any mode of their choice. I
had font-lock and thingatpt in my mind, but I didn't want to talk about the
implementation. After all, org uses font-lock under the hood for this anyway (or
am I too unfamiliar now? :)). It is just a convenience. In all of this cases, I
am thinking of those small minor modes be a tiny small "frameworks", where a
user can setup like very few regexes, or whatever is needed for a parser, and
have a "customized" syntax instead of going on through writing their own minor
mode.

I see. Thanks. Something like that for other features.

This is not the direction Org mode project is going. We do the reverse -
Org markup is getting more stable, with the aim to simplify developing
third-party parsers and eventually registering Org syntax in IANA MIME db.

However, stable Org markup does not mean that we cannot implement Org
mode features outside Org mode. Another general direction we are going to
is using parser APIs across Org mode. The idea is to encapsulate the
fine details of Org markup into the parser, only leaving some very basic
structures like recursiveness of markup objects exposed. In theory, one
may eventually just replace the parser with, say, Markdown parser (with
appropriate API), and get Org mode features in Markdown (well... except
that Markdown has fewer kinds of syntax and certain things do not exist
there)

I am not sure if many places (except Markdown) have a notion of link +
description. And the rest is supported by, say, Hyperbole.

What might be more interesting is generalizing Org previews: Org can
preview LaTeX and images, but we can think of it more generally - any
kind of text object might have alternative (possibly image)
representation. See https://list.orgmode.org/orgmode/87edbhljr7.fsf@hyperspace/

You are describing font-lock here. Users can already add custom
fontification in buffers by supplying regexps + face to be used for
specific text fragments. What is the novelty?

This idea does sound useful.
