yeah, but then with that pedantry applied the Honda S2000, BMW 3 Series, Mazda Miata, and various other cars are technically mid-engine.
FR/MR/RR is basically useless to talk about with regards to performance dynamics; HPDEs and driver coaching has taught me that 9 times out of 10 when someone mentions where their engine is sitting in the car by using FR/MR/RR , what they're really trying to get across is where they felt their center-of-mass was during the drive.
And to that point, a Formula style car might be mid-engine, but most have a suspension and aero adjusted center-of-mass that is as aft, if not worse, than any Porsche out there.
