> 1. Image recognition: many banking apps offer support for transfers via QR codes.

Accepted.

> I18n:

Outside of CJK, every new language takes a couple of kilobytes. You cannot explain megabytes with that.

CJK I already mentioned, it might be beyond reach? But actually in 1986 I saw the first IBM PC with a Kanji UI. I have no idea how much memory it had. But I might guess that might still have been hardware where 640 kilos(!) is more than anybody would ever need? Not sure.

> 3. Branding

I couldn't care less as a customer. The bank should offer good rates and flexible service. They can keep their branding.

> 4. Telemetry

Everything the user can do on their qwerty can be logged with kilobytes of code.

> 5. A/B testing support

Same here. Remember our interface is 80x25. Many variants of that fit into just kilobytes.

> chat with customer support

I started to use IRC in 1990. Don't remember how big the clients were and cannot quickly find a reference. I would guess 100 KB max, probably less. Using a camera would not be possible, we had that already under QR.
