No, this does not make thing more clear for me.
It looks like in order to create some 'preparatory patch' I need to
introduce new fields that are not actually used and create some code
for them that will be changed in next patch.
Is the goal to make the review faster? The code already has been
reviewed several times in details.
I expect this 'preparatory patch' will make things more complicated
and will spawn additional rounds of discussions.

It is hard to do as I do not understand the goal.
I'd suggest you to make any 'preparatory patch' that you find useful.
