Tasks can be in to the categories of Later and Someday/Maybe, i.e.:
  1. I'm committed to do it (e.g. optimize <name> module) but I would like to postpone the decision of when to start.
  2. I wish I could do it (e.g. redesign <app> entirely) but not in the near future, and sadly, maybe never will.
I would still like to see these tasks in my reviews in some frequency.
To implement this in ClickUp, one can unset start/due dates and: 1. add dedicated statuses 2. create separate lists under the relevant projects. Then, use (planned in your road-map) saved filters.
However, this makes the planning methodology a little fragile.
I think that planning is inherently related to start dates and that one would gain a lot of structure by implementing next/waiting on/later/someday as possible values of start dates.
In other words, a big player in planning is reflected in what you think is the time you should start working on a task and this should include some "soft values" such as:
next=first chance I get (useful also for micro planning, i.e. choosing tasks frequently by context)
later=soon but postpone planning it right now
somday/maybe=yeah, I wish I knew
Dedicated clickup planning tools and snoozing (https://clickup.canny.io/feature-requests/p/snooze-tasks-2) complement this idea perfectly, in my opinion (ignoring details). Because a dedicated tool would gain from this kind of structure in planning (rather than some unknown statuses/lists a user might or might not define for someday tasks).
