It's much more generic than that. It's highly flexible and intuitive hierarchical information organization software. At least that's how I'd describe it.
The innovation isn't the organized structures themselves either, but rather the intuitive non-technical interface for rapidly and concurrently updating both the information and structure. You can build a lot of Jira-like features but it doesn't dictate much of how you do that.
It does have a highly customizable Kanban view of their more generic database structure where each object is itself a page which can be filled with anything and everything else Notion has to offer (including more databases). Databases can have many views, structured as calendars, tables and a couple other forms I don't use, and each view can have its own set of filters, etc.
It kinda looked at Jira+Confluence and asked "what's the simplest fundametal software which can be used to build everything they have to offer"
