This assumes everyone is on exactly the same version. Larger organizations can afford to appoint SREs who can institute a broad range of security and optimization policies (including "all apps should use the same Alpine base image version") and enforce them programmatically as well as ensure that apps are continually updated to match them. That kind of thing is expensive, resource-wise, for smaller organizations.
