I'm guessing this was meant to be a joke about how everyone is still using the DIN connector for midi? Kind of confusing.

DIN MIDI connectors have the advantage to use mandatory optocuplers so no ground loops etc.

Lots of smaller or portable synthesizers use a 3,5mm TRS connector for MIDI. It's badly standardised though: there are different wirings depending on the manufacturer.
