I was not under the impression that this was a formal review of Boost.Async.
I rather was trying to understand the specifics of Boost.Async and therefor
I was comparing it to something I know ;)

Just to rectify this: HPX is not a product of a private company. It's just a
large open source project distributed under the Boost license with many
(very capable) people contributing, which because of its scale and the
produced code quality might have created your impression of it having a
commercial background.

The reason why it's not considered for Boost inclusion is simple. Nobody has
stepped forward to make that happen. We'd be happy to support anybody
interested in pushing such an avenue.

That was John B. IIRC, he was asking why you have decided to create your own
library instead of joining forces by contributing to HPX based on his
impression that Boost.Async provides services very similar to HPX.
