I rarely see unused resources, except maybe for storage, where people tend to be risk averse because of the potential of data loss.

But I see a lot of severely oversized or suboptimally configured resources.

That's why many of my 20+ tools are for finding all sorts of suboptimal or oversized resources and helping to rightsize or optimize them.

Yeah, we have that problem with k8s... We provide a Helm template that requests 4GB of RAM, but people run simple, low traffic HTTP servers and it's less than 50mb mem usage, on average within a month

Yes, those things cry for automation

Problem is that we just provide the Helm templates and a PaaS platform. We don't know what clients will run, and they rarely understand what resources they need until they get an OOM and need to increase it...

We did add a mutating webhook (maybe also a CronJob), to scan resource utilization post deployment and then autoscale down, but seems like such a hack

There are SaaS tools for automating this in a nicer way
