Nope, it could maybe read the USB ID, but that's just the type of USB-UART chip, which will be the same for many boards.
It's up to the board really. I guess it could store the baud rate in the WiFi settings area, so firmware updates wouldn't change it? That might be more sensible.
Well, that's kind of what we have. It remembers the baud rate setting, so if you connected to something last and it worked than you're sorted.
But that doesn't help new users. The IDE could ask the first time it connects, but honestly I find it hard to see why every single Espruino user (ESP8266 or not) should be inconvenienced because of this.
