Well, yeah. I mean, what else do you call stuff like...
https://mangadex.org/title/47398/a-kind-world
This? Where each chapter is 1-2 pages.
Or these, where each chapter is usually just 1 page:
https://mangadex.org/title/44625/this-croc-will-die-in-100-days
https://mangadex.org/title/46520/these-two-will-be-married-in-100-days
https://mangadex.org/title/46541/this-gyaru-will-date-the-otaku-in-100-days
Even if you don't think the 100 days meme comics count, what about stuff like Wonder Cat Kyuu-chan?

Every so often you see people complaining in the comments about these types of 1-2 page per-chapter comics, I just thought a format flag for them would be nice.
