Huh? They haven’t released a remotely small phone in years.
It’s not clear if they decided to move just add E models to their lineup, or given up on SE models entirely.
Similarly people have called the 16e as a replacement for the SE line, but that’s a cost assessment not one based of form factor. It could be most people bought the SE because it was cheap, but without two different form factors at identical prices there’s no way to tell.
Regarding the 17e, the supply chain rumor mill keeps mentioning it, so it definitely seems to be a thing.
