Intel clearly recommends NOT to defragment their SSD. You have had many answers telling you in great detail why this is so. If you are so compulsive about defragging that you can't help doing it to your SSD you would do better to see a shrink than to defrag your precious SSD and ruin it fast
With the price of SSDs dropping, and the price of shrinks, it's probably cheaper to ruin a few SSds, especially as you'd need more than one visit to the shrink!
Seriously though, the sugestion of a once or twice a year clean-up seems like it wouldn't do too much damage, although it's probably better to backup your SSD to another drive, wipe all pages, and restore, rather than running a defrag program which would probably write many pages several times.
It'd be interesting to see how a backup, wipe and restore affected performance of a heavily fragmented drive!
