If that is the case please file a bug and (importantly) include the supporting documentation, unless you can find an existing bug for this. As mentioned earlier the distinction between allowed and supported is important. With old XenServer versions, for example, you can add more disks than what is supported with xe commands, but if too many VMs in a pool have too many disks there can be problems.
