Our definitions of task priority levels could... be better.
The term "normal" is problematic:
- "Normal" implies a default. (For completeness, the initial default task priority value is "Needs Triage".) IMHO by default ("default" as in "most often"), tasks shall be low priority (due to resources being limited), but the word "Normal" creates an incentive to use that term instead of e.g. having to explain why something is "low" priority. The constraints of a realistic planning process might be slightly easier to explain if the term to compare with is "medium" instead of "normal".
- There is no abnormal priority to compare with.
