ie basic functionality I personally look for that I don’t think this would support would include:
* Projects with hierarchies
* Reminder dates
* Tags and contexts
* Multi-Step tasks
If there is a popular standard, it will remain popular. The trick is building up enough users that they begin to credibly demand an export to the protocol from big players like Atlassian.
Even if people do have the same model then the terms are often different, depending on how you learned to do things. (Example: What is the "correct" number of levels of tasks -> subtasks and what should each layer be called, i.e "Epics -> Stories -> Tasks")
We've been building out Shortcut (https://shortcut.com/) for several years now it's not uncommon for new leadership (new VP of Eng or VP of Product) to show up in a large organization (100+ people in eng and product) and decide that whatever problems the org is having can be solved by moving to Jira and forcing everyone into a new mental model around how they're building things.
(Side note: We're tracking the rate of success of people who make this decision and how long they last in the org, and it's [perhaps unsurprisingly] not great.)
We need ANSI pomodoros clearly :)
Probably not.
