I would think it did? ext4 is the most deployed when you don't need extra features, because it's very stable, seamless upgrading from ext3, universaly GRUB support, and has little surprises and is actually pretty fast. ReiserFS is mostly dead, btrfs isn't even really stable yet and is slower.
I wouldn't be surprised if XFS was the second most deployed filesystem after ext4.
Where it's really losing is to the "block layering violations" of btrfs. Being able to manage storage pools at the filesystem level like ZFS is a major feature advantage.
