Our discard implementation is meant to accommodate a wide range of devices. Just because some of the currently shipping low-end consumer SSDs implement TRIM poorly does not mean we're going to scrap what we have.

We are not in the business of designing for the past. Especially not when the past can be handled by a shell script.

Today, and tomorrow, and the next few years, that means SATA SSDs by the gazillions, as well as a relatively smaller number of enterprise behemoths. A shell script cannot currently deal with LVM, RAID, or btrfs filesystems.
