But that's true of anything that you end up putting "in the box".
Worth considering if you let folks open your device and
replace things that *they* think are FRUs (memory, CPU, etc.)
If one of your customers makes such an (inobvious?) modification
and pisses off a local Ham who then files an informal complaint,
etc.  It's relatively easy to piss through the monies you would
have spent on "certification" trying to diagnose and defend
*your* product.

Warts can be (and are) listed independently, to reduce
potential testing and deployment gliches. A listed
wart doesn't guarantee radiated compliance, only facilitates
conducted performance on that one, main, port.
