It surprises me that there were not much discussion about this "drawback" regarding TP, when trying to use it on machine and g-code with rotary axis moves. For example in my case I have to do an offer for milling PU foam pieces, where I could use higher speeds for cutting (like 2500mm/min), but unfortunately geometry of final pieces demands full 5-axis final cut where I can now reach only about 650mm/min, that means my machining time exceeds way over budget and I'm "out of business".

So if F=2 whole move with acc dec takes 30 secs. In my gcode processor I calculate it from speed/distance and unit is 1/min for each segment of toolpath. Beeing axis unitless it can be applied to axis with different distance units.
