Good idea Dmitri, this commit message does read like documentation.

In fact there's already user-oriented coverage in UsersManual.rst which 
is more or less accurate. So my write-up might be better adapted as a 
doc comment or section in InternalsManual.rst.

The situation on the ground is changing rapidly so will hold back a few 
days on this.

Alp.
