Gero answered that question in an interview before, when the Eurofighter was first announced (can't remember which but I think it was a Grim Reapers one) and iirc it was something along the lines of it'd probably not work that well, but they might integrate it and jokingly added that it would make it more realistic if it doesnt work that well.
But keep in mind this wasnt a confirmation and before the heatblur partnership.
