On my peugeot 5008, pressing the electronic parkong brake button for more than cca 500ms while driving fully engages all brakes of the car (not only rear ones), but ABS remains functional. So in an emergency, one could theoretically still use this as an emergency brake. Although I agree that it's quite dumb, because it of course wouldn't work in case of computer/electric failure. What a shame indeed.
