They say to replace them with Banners, which are just a different style of a "Toaster", just usually stay longer, or are permanent until the user takes an action.
No, it's different. A "toast" is a floating element, a "push notification" which is detached from the panel, e.g. can disappear quite quickly. The banner is placed closest to the context where the action is triggered, e.g. might require the user to close it. If you have some disability, e.g. cognitive, visual or motor, it's likely to be easier to perceive the information. When a user creates an "issue", the "issue item" is displayed in the list, meaning that you won't need a secondary notification process.
The main problem with toasts is that they disappear with no hope of recovery before you get a chance to read them, obscuring other content in the process. Banners don't obscure other content, don't disappear without user action, and could theoretically have a message history.
