Yes, it superficially seems nice and logical for netfilter to use ENOSPC when it runs out of space. But when that error code propagates up to the user, they see "no space left on device" and will then run "df" and wonder what the hell happened to their computer. The kernel makes this mistake a *lot*. EFBIG in the rtc drivers?
