In secure airgapped environments, very much so. We blew time setting up new offline install processes & tutorials for the Nvidia docker ecosystem for rhel8, which basically reused centos7, as most of our users took weeks/months when they tried to figure out for themselves. Think utilities, gov, banks, etc: Anything not supported by official RHEL8 repos causes problems both technical and compliance.
RHEL8 felt like a repeat of IE vs Firefox but now for RHEL (main sponsor of Podman) vs Docker, and much worse. It's one thing if docker was never there or containers were removed, but this was replacing with a binary-incompatible tool under their effective control and marketing to security-critical customers (and on hackernews) as a safe and ready replacement. So we also burnt time diagnosising people were trying to use broken podman tech because that's all RHEL gave them and tricked them into thinking was appropriate.
