I'm pretty sure this is for simple sharing of probably very ephemeral lists like a shopping list, vacation list, etc. If you got the link, you got the list. I don't think this is meant to replace reminders/tasks apps on android or iPhone
That's a good point, I never fully learned Notes. I just like using markdown writing longform stuff and the simplicity of a dedicated todo interface with shortcuts to quickly add them w/ dates etc.
Do we _really_ need an app for that?
