personally, that is what I am currently thinking along. I was calling them AbstractDTypes. These would also (probably mainly) be used for type promotion during ufunc calls (ufunc type resolution). OTOH, for `no_object` itself, I feel it would be OK with just special case it, since the I do believe the plan should be to deprecate it. I have to think a bit about how "flexible" dtypes come in (and value based promotion, which is a bit of a funny beast). I would like to plan a zoom meeting beginning of next week to discuss this type of thing a bit more. Maybe Monday at 11 California time, but right now I am very flexible, so whoever would be interested, feel free to shoot me a mail to move things. Not sure how concrete things will be, but without talking about it, it is difficult for me to settle design ideas a bit more.
