Hashtags are literally text, though? Sure, a lot of them will be just ships, character names, copyright names and so on (which are all form of text btw)... But look at the hashtag in post #6956829 ("#今年も残りわずかなので今年一番伸びた絵を貼る見た絵描きさんも強制でやる", DeepL translates it as "Since there are only a few days left in this year, I'm going to put up the picture that has grown the most this year, and I'm going to force the painters who have seen it to do it too."). Or in post #6203313 ("#線画と完成", DeepL: Line drawing and completion). Or the tags in this Tumblr post ("#my art #it's been a whole 2 years since girls in the hood was released! wow! #actually a complete coincidence that i was able to meet this anniversary :') glad i could though!"). All of those could be put into the posts without the # and they'd still be relevant.
I don't disagree that, while in the strictest sense of the words, a hashtag is indeed text with a link associated to it, currently it's treated as less important/valuable than true, non-link text (ie they don't count when symbols are present and are ignored for the purposes of symbol-only_commentary - we may need somebody who knows how that tag got made/defined/updated to give input here)
I feel you that it's true that sometimes the hashtags can have more elaborate things that could be of interest or even add meaning to a specific picture, but without any hard data on it and just from my time working on doing commentary TL (if you can even call it that, considering how minimal the TLs I can do are), the impression I get is that they're not really useful/relevant the majority of the time, hence them being relegated to their own subclass of commentary. In the hierarchy of "relevant" things, it's at the very bottom... but imo the tag should not be nuked, since it's the only indicator we have to indicate that -something- is in the commentary, even if it's the kind of thing most people wouldn't derive much use from as things currently stand.
