{{[[Template:etyl:nah|etyl:nah]]}}
Do we actually want this? Functionality-wise, it doesn't do anything, in that {{etyl|nah}} would display the same thing and categorize to the same category and link to the same Wikipedia article even if we deleted it; but maybe we want Category:ISO 639-5 templates to include all of the ISO 639-5 codes? (I ask because a certain widely transcluded template was recently changed to assume that if there's an etyl: template for it, then it's a language family and its only entries are in proto-language appendices. Obviously that change made {{etyl:nah}} very problematic. I've reverted that change until discussion has taken place, but it or something like it might end up getting implemented for real, so if we don't have a particular reason to keep {{etyl:nah}}, then maybe we should get rid of it. I've already taken care of {{hbo}}, which was the other problematic case; aside from those two, there are a few pairs where {{foo}} and {{etyl:foo}} both exist, but none of them are cases where lang=foo is reasonable anyway.)
