I was surprised by it. I was expecting for Tab to have a local scope. It was 
surprising to me that it affected all the sections at the same level below 
that paragraph. I was expecting a behavior similar to what it happens for 
lists and enumerations.

The current behavior is also surprising in the sense that, at least in the 
examples I tested, Shift-Tab works by promoting a (sub*)section but Tab does 
not demotes it (at least here it is consistent with listing and enumerations).

Also as it is if we have:

1. A
2. B
2.1 C
2.2 D

And press Shift-Tab in 2. we get:

1. A
2. B
3. C
4. D

My expectation was for this to become a no-op since it is not possible to 
promote 2. B anymore.

Is this the feedback you are expecting?
