We're never going to get this right, are we? The only person who can decide on a system's appropriate setting is the operator of that system. Haphazardly increasing the limit every few years mainly reduces incentive for people to get this right. And people who test their software on 5.17 kernels will later find that it doesn't work on 5.16 and earlier, so they still need to tell their users to configure their systems appropriately. Until 5.16 is obsolete, by which time we're looking at increasing the default again. I don't see how this change gets us closer to the desired state: getting distros and their users to configure their systems appropriately.
