  That's always true. But UIs still need to be simple.
  No need to teach the user the differences of a :CLOCK: vs a :PROPERTIES: or 
drawer vs. metadata. Users who type can do a simpler distinction:
  1. things you type yourself
  2. things that appear/change/disappear after invoking org functions 
(C-something, S-something, M-something). E.g.: the words SCHEDULED, TODO, 
CLOCK, PROPERTIES, EFFORT, checkboxes [ ], timestamps, …

  I speak for myself, but I expect class 1 not to be changed by org, and class 
2 to be handled only by org (I can always edit manually, but I shouldn't need 
to do it). I know that you can actually type everything in class 2, but you 
shouldn't NEED to.  
  Any other opinions are welcome.

  Indentation is for me as important as the other letters I type. I don't want 
it changed.
  It's a personal preference. Emacs respects it to great extents.

  Maybe I should clarify that I see the text inside my org files as a tree of 
knowledge. The position inside the tree of a particular item does not affect 
how I write the text (e.g. how many indentation spaces). I can move nodes 
freely from one place to another and I have no indentations to fix. „Tree 
structure“ and „item content“ are disconnected.
  If you really need other sources, you can see how tree operations in other 
contexts don't modify the contents of each node: 
http://pythonhosted.org/ete2/tutorial/tutorial_trees.html#concatenating-trees
  I wouldn't want titles, clocks, IDs, indentations, properties, priorities 
etc. changed when the tree structure changes.
  Maybe other people think the same; you can survey the list.

  The only one: indentation is added:


After demoting, it changes from this:

**** some
        :CLOCK:
        CLOCK: [2013-11-12 Sel 10:45]--[2013-11-12 Sel 11:40] =>  0:55
        :END:
Text



  to this:
  
***** some
         :CLOCK:
         CLOCK: [2013-11-12 Sel 10:45]--[2013-11-12 Sel 11:40] =>  0:55
         :END:
 Text


This will happen in all subtrees.

  That's similar to a not-so-bad old behaviour. But it's still a bit better (it 
avoids the problem described in 
http://permalink.gmane.org/gmane.emacs.orgmode/92450)

  I do the typed-by-me/not-typed-by-me distinction.

Ok, make it:

2. With org-adapt-indentation = 'partial, new lines added by org
(:CLOCK: drawer, CLOCK lines etc) are indented at the same level as the element 
above.
