And I, for one, would expect that. And _want_ that: I want the code to
do what I said, not have some magic which silently/invisibly intercepts
ExceptionGroups which contain something buried deep in their subgroup
tree.
We already allow "deep" exceptions out, to be caught at an arbitrary
outer call stack level. I don't see why ExceptionGroups should be any
different.
I certainly do not want ExceptionGroup([AttributeError]) conflated with
AttributeError. That fills me with horror.
