Hi Hameer, all,
sorry for the super late follow-up. Not that there is any content, but I just put this up quickly:
a bit also because I am not sure if the zoom link will work, so I want to be able to update it.

Hi Sebastian; all:
I plan to attend the dtype meeting. Monday 11 AM California time is fine for me.
Best regards, Hameer Abbasi

The possibility of disabling default creation of object arrays has come up again. I'm wondering if one way to get there is to allow generic dtypes. The `numpy/core/numerictypes.py` module defines a hierarchy, and if we could allow things like `dtype=integer` or `dtype=no_object` and such we would gain more control over the resulting array types. At some point we could make `no_object` the default if we so desired.
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.
