I tend to agree but I think toasts can still be useful and good UX. Putting useful and actionable feedback in context instead of toasts is a rule of thumb that I try to follow but it's not always appropriate.
For undo-able actions, toasts disappearing too fast or colliding with other toasts badly is a real problem. An affordance to see the toast history with non-disappearing undo buttons may be more to implement but for a lot of apps, a viewable and editable history combined with toasts is a much better UX than either system on its own.
