JK vs Helm vs Kustomize vs TK vs Jsonnet

[alexec]

I've created an issue for JK with Argo CD. There will be a few bars it'd need to pass to get there, e.g. uptake (https://star-history.t9t.io/#jkcfg/jk), community interest (thumbs-up on the issue), and feature comparison with existing tools. What can JK do that other tools cannot?

It'd be good to have these documented by the JK team.
