Higher inductance value = REQUIRES longer dwell times to reach a specific charge level.
The worse conditions for firing the spark plug is at WOT, lower RPM range, and a HIGH engine load, RAPID acceleration. So not fully charging a coil at maximum engine RPM is not necessarily a design flaw.

But peak cyl pressures in our 3.2L cars happen at WOT 5400-6000RPMs (peak torque) and even the stock design is a compromise here if the system voltage is below 15v. Putting in a coil that needs more time to dwell is a bad idea as it makes this problem worse.
I won't argue if a coil should be fully charged or not but I will say that the stock setup fully charges the coil so long as time permits. That's what the engineers designed in the 84-89 DME. I do agree that some other EFI system play with dwell times to reduce charge for low cyl pressure conditions but the 3.2L does not do this.
