Debian is notorious for having a stale and/or custom lvm2.
Generally speaking, it is recommended that lvm2 not be older than the
kernel (but the opposite is fine).

Given the narrow scope of users impacted (read-only snapshot creation is
very niche, certainly not the default): I don't think it is worth making
fiddly changes in dm-snapshot to warn the user and override the
permissions for the cow device.
