For the record, N-API (Node.js) doesn't look horrible to integrate
either; certainly better than how unfriendly embedding V8 directly
looks.

The benefits would be that we get V8 (latest ECMAScript and jit), but we
lose the charm of being able to ship with very own script interpreter
sources (I'm thinking of my poor i915gm that ran out of disk space ages
ago. ;)
