I think discard is not recommended generally, esp. with buggy SSD firmwares where it could end up resulting in filesystem corruption. fstrim is the way to go.
On what timeline, in what conditions, and is it applicable to EBS, which isn’t directly backed by just an SSD? While it’s very easy to pigeonhole yourself into absurd costs with cloud, getting an ephemeral VM up to run a task that takes minutes and then gets destroyed afterwards lets you make some decisions that would be bad for a longer-lived machine.
