1koma is supposed to be for one-panel comics like post #6017020, but from a glance it's overrun by a number of other very generic concepts and seemingly added at complete random to some posts.
- Posts from series pools or parent/child chains that aren't multiple_views (post #6004579, post #5965772)
- Greyscale posts, because they resemble comics by being greyscale (post #5677939, post #5833838)
- Posts that contain speech bubbles/dialogue, because comics also contain speech bubbles/dialogue (post #5937435, post #5956380)
- ??? (post #5802282, post #5956498, post #5903234)
We should follow the current definition in the wiki, which mentions it needs to be an actual panel a la post #6017020. It's already this much of a mess even with that rule in place; if we give the go-ahead to add clauses for some of the above concepts then it would truly become a wild west of a tag, with users twisting said clauses to justify essentially any post being 1koma. As evidenced by my examples, some users already seem to be doing this; imagine if we greenlit such a practice.
There's also a seperate issue with 1koma implying comic, meaning that users removing the 1koma tag routinely don't notice they also need to be removing another at the same time (post #5483979, for example). I don't really have an opinion on whether we should keep the implication or not, just figured I'd mention it (if only so future tag gardeners don't end up doing half a job by accident).
