Right, mdadm should skip those. For me, I also want the option to not add at least fd0 to /proc/partitions but that's nothing to do with mdadm (I maintain a portable emergency boot disk that has to work on countless unknown system configurations). That is the way it was before updating udev which now needs devtmpfs. I already patched mdadm to ignore the floppy and cdrom device types so at least it doesn't hang on boot, only when things like fdisk -l are run.
