Seems that things change, but according to the FAQ, there are still some issues with this matter (know how much Space left and use it)
Il still think that mixing réplication (raid) and file system is a very bad idea.

This break the "layer" model. i have 3 layer : raid, volume management, and fs (Can Swap the two first). If one of them is upgraded or replace by another, no problem. This also respect the unix philosophy : do a single thing, but do it well. Computing had always used layer model (network...). Because it's good and reliable. And for me, keeping my data safe is the most important thing.

Just checked this link, thanks.
Metadata miroring is a FS feature. For exemple ext4 make many copy of the superbloc. Guess that one day ext(5?) will offer more. In fact, I don't feel the need to have multiple copy of metadata because :
hardware problems (badblock) can't be an issue anymore with raidX
Logical problem (silent corruption) is also an issue already solved by mdadm with raid6. (callded "self healing" on synology link)
For last feature, snapshots >LVM.
