It is not really about disabling some feature, it is about not implementing the feature.
Microdrives are, on a logical level, just normal HDDs, with MBR (=master boot record), partitions etc. Apple could just modify their "big ipod" firmware drivers a bit in order to get it running on ipod mini (just because ipod mini is based on a different hardware).
On the other side, CFs are on a logical level something like floppy disk, without any MBR or partitioning. So running existing firmware from CF requires writing a new bootloader, maybe logical disk manager etc. It is perfectly reasonable that apple didn't wasted their resources to implement CF support to make life of ipod upgraders easier.
