The braid tags are all a mess. Is Izayoi Sakuya's hairstyle twin braids, side braids, or braided sidelocks? Is Kirisame Marisa's hairstyle a single braid, a side braid, or a single braided sidelock?
The creation of braided sidelocks and single braided sidelock means that now we're supposed to be making a distinction now between sidelocks and non-sidelocks, but this distinction is not always easy to make. The distinction is supposed to be that braided sidelocks go in front of the ears while side braids go behind or beside the ears, but in practice it's not always easy to tell when the ears are obscured. The position of the braids can also vary by depiction, so a single character can have their tagging split between side braids and braided sidelocks. Not to mention that every character tagged twin braids now needs to be tagged either side braids or braided sidelocks, depending on the exact position of the braids.
There's also the question of whether single braided sidelock should imply single braid or single sidelock or both. Recall that braided ponytail doesn't imply ponytail because that would leave us no tag for regular unbraided ponytails. This suggests that single braided sidelocks should also be kept separate from regular unbraided sidelocks, but braided sidelocks already implies sidelocks, so we've already gone back on the idea that braids should be kept separate from non-braids.
Meanwhile, single braid historically was often used for the dead mom hair over shoulder hairstyle, which we don't have any other tag for, so if we take the next step and make single braid an umbrella tag for single braided sidelock and single side braid, then it makes that hairstyle even harder to find and necessitates making some kind of new braided ponytail over shoulder tag for it.
I don't really know what to do here besides to say that someone needs to go through all the braid tags and think through how they should be defined and organized. Otherwise we get into these messes where we have too many overlapping or poorly defined tags and it's not clear what the difference between things like twin braids and side braids is supposed to be.
