...that's it? What about hooks being an anti pattern? What about upgrades potentially resulting in blowing away your whole deployment without warning? What about a lack of diffs or planning changes? Or the complexity/kludginess of go template logic? Or the lack of ability to order installation of resources or processing of subcharts? Or waiting until a resource is done before continuing to the next one? Or the difficulty of generating and sharing dynamic values between subcharts? Or just a dry run (template) that can reference the K8s api?

There's a ton of pitfalls and limits. It's still a genuinely useful tool and provides value. But it's mostly useful if you use it in the simplest possible ways with small charts.

I just wish the "operation engine" were decoupled from the "generation engine", and pluggable. I like how it watches the deployment, has atomic upgrades, can do rollbacks. But if you want a complex deployment, you currently have to DIY it.
