Right now I'm assuming that it does not draw in oxygen through the exhaust pipe, exept when starting. Logic is that EGR must be shut down for starting, because otherwise it leans out the starting mixture.

Definetly there are some dawbacks for this approach, I'm hoping i can live with those, and benefits are larger, compared to. I am sure this is the field that is thoroughly explored, but unfortunately by the people who are unwilling to share their test results. So to all others this remains unknown.
There may be some kind of compromise:efficiency vs. short maintenance interval.

This is exaxtly what I am talking about
: I like that EGR gasses are cleaner and cooler
