I'm still not completely sure why you are using the existence of a particular document as a criterion. Such documentation may well exist within Goenka's organisation. Sayadaw Mahasi's Progress of Insight was, according to the introduction, originally intended simply to guide his assistants.
Furthermore, there are many meditation teachers who do not make much use (if at all) of the Visuddhimagga progress map.
I think that it is quite reasonable to say something like:
"I'm following teachers who use this map and this approach, so I'm not going to worry too much about those who don't, and I can't really comment on their approach."
But you seem to be going much further and saying:
"Teachers who don't provide this specific map in a way that is satisfactory to me are not teaching correctly."
There may be other reasons for doubting whether particular teachers are teaching correctly. They might, for example, make claims that are in blatant contradiction of the suttas. It could be useful to point that out. But to dismiss someone for not talking enough about the insight maps seems a little odd. It's not something that teachers would normally spend much time discussing with their students in any case.
