I considered it, but I have some problems with the Arch LTS release cycle. If I were to choose an LTS kernel, why not just dump Arch and go with an Ubuntu LTS, which has better long term support?
The other problem is that at the time, the ZFS packages for LTS were pinned at a version that had a known issue with arc_reclaim encountering a deadlock essentially causing the file system to become unresponsive after a substantial transfer (think rsync).
Now, obviously, it wouldn't be that difficult to modify the PKGBUILD to pull a newer version of ZFS, but there's a point in time where the maintenance required to update starts to outweigh whatever benefit you can glean from the LTS kernel.
That's not the case now since the LTS packages appear to be at v0.6.5.9, which has the fixes, but I don't remember this being true about a year ago.
