There's a nasty assumption wrapped in that sentence that isn't quite
fair. We've always wanted projects to innovate, but the choice of common
language was entirely designed to put people in a box that was easier
for operators to consume and debug.
I don't see an actual real problem statement that takes operators and
users into account in that etherpad*. IMO language bindings is a red
herring, we have REST API's and they're not so bad that they have to
be wrapped in convenience libs *cough*OaktreeShade*cough*.
I'd really like to see *users* and/or *operators* be the focus of any
efforts around Golang, or Lisp, or anything else we ship.
Designate felt that the operators were better served by a Golang
transfer daemon (IIRC). Hummingbird was created by Swift operators to
deal with their IO concurrency problems. I _like_ those efforts (now
that I understand them, which was not easy). But the etherpad kind of
reads to me like "let's make Go things because container things".. maybe
somebody can explain it to me like I'm 5?
* Kolla is a deployment project, and imo, can do Golang the same way
openstack-ansible does ansible and puppet does puppet.
