Not true - the cost isn't zero.

Of the top of my head...

#1 The project will mix and blend with other programming models - The
shared runtime should cover all the popular stuff and "this"

#2 User confusion - Promoting this over other more established
projects and models is just another turd in the pot

Lots of things are interesting.. lets take Legion as an example.. that
little heard of project at *least* has a bunch of examples and more
docs than SE..
https://github.com/StanfordLegion/legion/tree/stable/examples

Why do I feel so strongly - because I've been dealing with
here-today-gone-tomorrow programming models for 8 years now... It's
boring and wastes a lot of time. Research projects should incubate
outside the tree before being included with production parts.
