Part of the issue is that bluetooth as a whole is nothing more than a wireless serial connection. It's the various protocols built on top of it that determine its stability. The Bluetooth SIG only really control the pairing between the two devices, a low layer. You're hoping that the company you buy stuff from has implemented the protocol correctly, over which the SIG has no control.

Traditional "slow" IrDA is essentially HDLC over UART with packed based protocol stack over that, that among other things can emulate dumb reliable duplex pipe (TCP-like) that is usually exposed as virtual serial port, bluetooth is similar, with significantly larger set of "other things". Other relation to serial port is that it is usual interface between the HCI and host system (using fairly highlevel protocol). In the lower layers it is frame based protocol that has no relation to serial ports.
