I do have some reservation in taking out /proc/<pid>/cpuset by default as

Cannot be /proc/$pid/cpuset declared a v1 feature?
Similar to cpuset fs (that is under CPUSETS_V1). If there's a breakage,
the user is not non-v1 ready and CPUSETS_V1 must be enabled.
I think we can try given that the config is providing an exit path. After
all, users who were depending on cpusets on v1 are in the same boat.
I am not totally against this, but I think we need to make the
relationship between the CPUSETS_V1 config and /proc/<pid>/cpuset file
more visible if we want to go this route. We should update the help text
of CPUSETS_V1 config entry to emphasize this.
