Yeah - removal of the EGR and intake just to get to the PCV sounds like "type 2 fun".
I'm guess now that I know the car has this deal too, I should add to my service plan to also do somewhat more frequent coolant drain and fills to keep internal corrosion at bay (30k or 3 years maybe???). Suppose this is something I could do.
For the transmission with the pendulum torque converter I will take your advice Calisto, I think you said every 15k drain/fill (which I can do) and every 30k pan drop to replace the filter (mechanic does this, over my pay grade).
Also am putting in a "top tier" gas mandate for my daughters to follow. With 3 of them sharing the car that's like corralling cats, but I will try. Maybe a shot of Techron in the tank before oils changes too (probably this a placebo since we are talking DI).
We should get a petition to Mazda on the CD to allow it to be user controlled. I'd even be happy with a software patch that deactivates it when Sport mode is engaged.

Even on pre 2020 engine the PCV is not a fun task to clean. But thus far I have scoped enough post 2016 Skiactiv engine that I don't see an issue with the system at least up to around 170k miles. There is some small accumulation oi oil film that eventually coat the main body of the intake but as far as I can see it does not vaporize and continue into the combustion chamber enough to be alarming.

^^^^This is a very easy service to do with simple garage tools and a pair of RYNO Ramps ^^^^
