Well /remind works in exactly the same way and you can tell it to remind people or channels etc. The fact that it shows as a reminder, not a message as if you just typed does matter in some contexts, but I certainly make heavy use of scheduling reminders in channels when it's important to follow up on something. For me I think this tool would be better when for example you know it's a birthday coming up and you want to write a message now. It always bugged me that Facebook doesn't let you do this either (although it is obvious why FB want you to have to come back). But I guess the funny thing about Slack not offering this is they have all the code / infra / text parsing they need to do it, it would surely be trivial to add.
