It would be possible to provide a set of combinators along the lines of 
the examples presented in the JEP. It turns the feature into a set of 
"utility methods" and doesn't help with the main goal of promoting 
usages that address issues around cancellation and shutdown. It's also 
somewhat unsatisfactory when trying to do something that is a bit 
different to one of the canned policies.  So yes, we've been there but 
decided against that direction.
