Even if the threads were seized, you should have been able to break it loose before rounding the flats on the pedal. The crankarm aluminum threads will strip out before the steel axle on the pedal gives way.
They had gotten rounded before I got my pedal wrench around it. The wrench was a Park Tool PW-4, a tool I use quite a bit. We also tried other wrenches and ended up with vise grips before power tools.
I have removed a lot of pedals as well, maybe not quite as many as you but then again I haven't been doing this for 40 years so I have some catch-up to do ; )
