My quarry and lake training more than prepared me for diving in the Ocean. Not because of the challenges but because the instructor chose to pass on the information I needed to make an assessment of whether the dive was within the limits of my training and experience.
RSTC Guidelines say absolutely nothing about conditions in which one trained being a determining factor in what environments they should dive in after the cert. What they do say is that a diver should be able to dive with a buddy of equal training and experience without the guidance of a professional.
Given that, all dives get logged in some way or another depending on the dive. Some are logged now in my notebook. Others get written down in an actual dive log when there is a need to do that. As an instructor, I am supposed to be a role model. Every agency I am aware requires the instructor to have students log their training dives.
For an instructor to state publicly that they don't believe in logging every dive, or that some dives should not be logged because they are not "real dives", is an instructor that I would not want to train with or allow a loved one to train with. What other information are they now deciding is not important?
I train in quarries, I train students in quarries. Many of whom are going to dive the Great Lakes with similar conditions. Or like I did early on are going to go to a warm water location with up to 10X the vis they trained in. To say that quarry divers need extra training is not true. If they were trained right in the first place. That includes giving them the knowledge and the tools to decide if an ocean dive is beyond them.
