Meta tag suggestion: name-only commentary for commentaries with names only and nothing else, like how symbol-only commentary is for commentaries with symbols only and nothing else.
These posts will tag english commentary if originally written in Roman/Latin alphabet. (Exception if they fall under languages other than Japanese/English and have localized English names.) (Forgot the wiki excludes names, thankfully I don't have name-only English mistags.)
You will then be able do a negative search commentary -name-only_commentary to exclude name-onlies. Though, we're pretty much ignoring names anyway... And who would be searching for names....
