There really are quite a few implementations out there... I had no idea. For example, the rust impl [jrsonnet](https://github.com/CertainLach/jrsonnet) has even more impressive (and more robust!) benchmarking results, and it...

Looks like `jrsonnet` works out tof the box as a drop-in replacement (eg. `pip install jrsonnet` works without needing any special build environment, then `import rjsonnet as jsonnet` and you're...

Could we publish a separate docker image with gojsonnet? Or always include the gojsonnet package but have a cli flag to enable it? Happy to submit a PR for the...

Imo we have the following options: 1. Ship an _additional_ `gojsonnet`-enabled docker image (eg. `kapicorp/kapitan:0.30.0-gojsonnet`, or maybe even more official via a new image name `kapikorp/kapitan-gojsonnet`) 2. ~_Always_ install `gojsonnet`...
