This is a missing feature of Reminders. In both Things and OF one can set a defer date (in Things that is the “When” date).
While I’d like to have that feature, "for me* (I’m not attempting to speak for others) not having it is not a major problem because I’m faithful with my weekly review. I’ll also use the Flag feature to “alert” me for items that I don’t need to start yet but soon will. Anything Flagged means start working on it soon or now. I’m stingy when assigning Flags. Out of 184 tasks, I only have two flagged.
You could also use the Smart List feature and assign relative dates, e.g., anything starting in x weeks/days. These are similar to OF perspectives. For example, I have a Smart List called “This Week.” It shows me everything I need to work on for the week. I set these dates the Friday before during my weekly review.
