This is a function/property of hardware, so it's IMO not desktop specific at
all. Servers suffer just as well from hard disks becoming slower.
This will also
trim thin LVs on thin pools (if any), right ?
So not just hardware, it can even make "software" storage layouts faster
& potentially even avoid pool exhaustion in some cases. :)

Incidentally I worked on that on the Ubuntu side 6 years ago:
https://blueprints.launchpad.net/ubuntu/+spec/core-1311-ssd-trimming This still
has the "discard vs. cron job" pros and cons and benchmarks, so might still be
useful.
Thanks!
