We introduced task subtypes in T93499 / T224417.
I don't understand what some subtypes are good for, especially deadline. Deadline is not a task type.
Many task types can have a due date though.
Deadline is set/used by forms 37, 54 and 94.
Some tasks get created with the Deadline subtype and I have no idea why. They do not have any Due Dates. Examples: T332743, T334770, T197015.
Need to check though which edit forms allow setting/editing a Due Date on a task. Unfortunately Phab doesn't offer a simple way to check which form was used to create a task.

- T310188: Due Date stamp rendering requires "deadline" task subtype; does not show for other task subtypes though Due Date field is filled

- maybe also T367830: Herald rules H295 and H301 broken as their conditions list custom "date" fields somehow not supported by Herald.
