@lmolkova thanks for your time and feedback, appreciated.

Let's move naming discussion back the other PR to where there are the rest of the stakeholders, so we don't have to duplicate the same explanations twice.

I will update this PR once we reach conclusion there. I will also add more links and explanations later.
