Partitions or no partitions?

After setting up a btrfs filesystem with two devices in a Raid 1 profile I added two additional devices to the filesystem.

When I run btrfs filesystem show I can see that the original devices where partitioned. So /dev/sdb1 for example. The new devices do not have a partition table and are listed as /dev/sde.

I understand that btrfs handles this with out any problems and having a mix of not partitioned and partitioned devices isn't a problem.

my question is should I go back and remove the partitions from the existing devices. Now would be the time to do it as there's isn't a great deal of data on the filesystem and its all backed up.

I believe the only benefit is as a learning excerise and I'm wondering if its worth it?
