Dropbox reversed its stance on this. It added support for ZFS, XFS, ecryptfs and btrfs:

They say ecryptfs is only supported when it is backed by ext4, which is a bit strange. I wonder if that is documented just to be able to close support cases when ecryptfs is used on top of a filesystem that is missing extended attribute support and their actual code does not actually check what is below ecryptfs. Usually the application above would not know what is below ecryptfs, so they would need to go out of their way to check this in order to enforce that. I do not use Dropbox, so someone else would need to test to see if they actually enforce that if curious enough.
