It seems he did two classes on the MN over the years. One is available at @Khemarato.bhikkhu 's online university. Another is available on YouTube in a playlist of 221 videos. I believe this earlier class is the one also featured on bodhimonastery.org. It was not comprehensive in the beginning, and it seems that BB added a followup class covering the remaining Suttas.
However as far as I see, MN25 is absent from all of these materials.
Is it because some of the details of that Sutta are too delicate to the orthodox view - or in contrary, that BB thinks that the Sutta is unessential?
I believe the Sutta does have its problems. Mainly the implication that Mara’s food is essential for physical survival.
His students call him “Bhante Bodhi” of course.
And if there ever was not an occasion to bother him with a question this could be it. He is very busy doing good Dhamma work and I don’t see the point in asking about this. Just my opinion.
One thing that always impresses me about Bhante as a teacher is his humility. He’s very willing to say if he doesn’t know something or even that he doesn’t “fully understand” a certain sutta! Which makes sense… The Buddha’s teachings are indeed deep, hard to fathom. It’s the Buddha! If only more people had that kind of humility with respect to the suttas!
It is even more impressing if you consider that his approach is “scholastic”, meaning that he views and interprets each Sutta according to the full body of doctrine. He is certainly a man of great answers to the serious student.
As @Snowbird said, we should really not jump to conclusions. He has not shied away from discussing very complex Suttas in the past. MN49 for example appears in both of his classes.
What is interesting to me is that MN25 seems like a “spinoff” of SN 1.1, the very description of the “middle way” that some historians believe to be the most historic. So I still do think that asking him would be justified.
