it's not a PaaS per say but Hashicorp new product waypoint looks promising at least when it comes to deployments. A common deployment interface over several of the tools we love/and hate(docker, k8s, nomad,...) making them feel like good old heroku. The operators are probably going to keep wrestling with the underlying complexity but at least the developers won't need to add yaml dev to their CV anymore(HCL is much better in my opinion).
I think we have passed the first stage where people have gone through a couple of disasters and have learned they actually didn't need majority of the features k8s offers at their scale. They are now actively looking for simpler tools which opens space for nomad and co. Plus success stories from companies like https://fly.io(yes I like them) with nomad are pilling up.
Caddy v2 seems to be doing something right although I don't think it comes with the same number of features out of the box. Plus it's more of http reverse proxy.
