I had no idea about cmc back when i was doing lots of testing here in the field behind the house Eddie, i was in my teens,

i had isolated antennas and choked coax but not because i understood cmc, not using the right size choke and never to my recollection did both at the same time,
i just liked experimenting,

i remember a time when changing my coax length changed vswr so at that time and probably others i did have an issue with cmc, how much it effected the result i have no idea,
i cut mine in electrical 1/2 waves,

i think the efficiency of the matching device will play some part & some antennas will be more prone to cmc issues than other designs,
don't know how much or how you accurately model something like a silver rod or clr2 with the farty little pcb coil.
