I went ahead wasting some time and hacked up `arc-lite` for fun:

  https://github.com/haskell-infra/arc-lite

It's currently at 407 Haskell SLOCs according to sloccount(1), and
emulates the `arc` CLI as a drop-in replacement. As a proof-of-concept
I've implemented the 3 simple operations

 - `arc install-certificate`
 - `arc list`
 - `arc call-conduit`

If we wasted even more time, this could result in

 - Simplify installation of Arcanist for GHC contributors via Hacked
   (i.e. just `cabal install arc-lite`)
 - Implement a simple `arc diff`-like operation for submitting patches
   to Phabricator
 - Implement convenience operations tailored to GHC development
 - Teach arc-lite to behave more Git-idomatic
 - Make `arc-lite` automatically manage multi-commit code-reviews by
   splitting them up and submit them as multiple inter-dependendant code-revisions
 - ...

Any comments?

Cheers,
