Generic parameter of StructuredTaskScope

[Attila Kelemen]

Hi,

There is an inconsistency in the treatment of the generic parameter of
STS. Namely, that while it was deemed important to know the common
base type of the result of the forked tasks; Surprisingly, its two
common implementations do not provide this feature. How come that in
the STS implementations believed to be used almost always are not
believed to find this feature useful? I mean, in the use cases I can
think of relying on this generic parameter, I would happily rely on it
even in the default implementation.
