Depends who you ask. For someone running lots of containers, it’s pretty crucial.
There are better alternatives, podman is daemonless and rootless by default, comes with a docker-compatible CLI, and far better container network implementations. It is also provided as stable/LTS package in Debian repositories so you won't have to upgrade your container runtime every 2 days (causing downtime), like running the upstream Docker package does.
The only reason to keep using Docker nowadays is if you have a lot of legacy apps that depend on Docker-specific features (e.g. require rootful containers). For most workflows it is a matter of
alias docker=podman. If you use docker-compose, you do need to port your setup to podman quadlets, or systemd-managed containers though. For me it was worth it.
