Thanks Stefan and I agree. I also think this is in general exactly the
direction current org maintainers/developers are taking. 

At this point, considerable work is being done (by Ihor and others) to 

- Implement a concise and efficient parser. This has also involved
  refining and clarifying org syntax, which has had some holes and
  ambiguities. 

- Replace org's largely regexp based font locking mechanism with one
  based on the parsing and tagging made possible by the org parser. This
  should improve both performance and accuracy in parsing. 

- Improving efficiency of folding etc

- Improving efficiency with respect to larger org files through the use
  of caching etc. 

- Increasing org's use of built-in Emacs capabilities rather than using
  org specific implementations. For example, adopting transient instead
  of an org implemented module which replicates similar functionality. 

- Increase modularity an enable loading of the functionality that you
  want. 

In particular, the important work being done by Ihor wrt folding,
parsing and caching will provide a core of functionality which can be
used to define something like an org minor mode which could be used in
those situations where we want some basic org functionality, like
folding, navigation and formatting/presentation, but we don't need all
the additional advanced features, such as babel, todo and time
management, spreadsheets, tables and table formulas etc. 

Of course, to what extent Emacs will/should leverage off org mode is a
completely different debate.
