Being able to shut JiffyDOS off completely is different to CMD producing 
hardware that swaps between 1541 ROMS and an actual ROM overlay at run time.

Anything incompatible with JiffyDOS would need it to be disabled either 
way, swapping between the 1541 ROM and an overlay would operate exactly 
the same because the same values would be presented to the CPU. There 
just wouldn't be the need of copying any of CBM code.

It might even have been possible to have tape and rs232 plus jiffydos 
all active at the same time.

If the drive manufacturers were able to sort out the legal issue of 
shipping 1541 roms, they wouldn't have been buying JiffyDOS licenses in 
the first place.

The drive manufacturers must have thought that licensing JiffyDOS solved 
their problem completely or they wouldn't have done it.

Good faith is not what comes to mind.
