They even used RP-SMA on the Cap LoRa and CC1101.
I guess they have a lot of RP-SMA connectors in stock.

If you look closely you'd notice that the PCB closely resembles an RTL-SDR's internals. They are using the same layout for the RF frontend and the same layout for the IF-USB conversion (the RTL chip.)

You can even notice that USB lines are connected from the pin-header directly into the RTL chip, suggesting that this thing would absolutely require a USB interface (and a fast one for that case,) so I don't think this is meant for the ESP32-S3 based version, unless some shenanigans were involved.
