Quill supports a number of formats, both in UI controls and API calls.
By default all formats are enabled and allowed to exist within a Quill editor and can be configured with the formats option. This is separate from adding a control in the Toolbar. For example, you can configure Quill to allow bolded content to be pasted into an editor that has no bold button in the toolbar.
