No, it’s very flexible. If you need to present complex relational data to clients in an easily digestible form, it has some nice tooling around that now in addition to basic views - Interfaces, they’re called. It doesn’t have the permissions granularity of rolling your own, but it’s surprisingly useful. We also built a custom CRM in it.
I also use it for personal things like aggregating transaction histories across financial institutions, personal contact management, etc. Although Notion has eaten its lunch a bit here imo.
Turns out that a web-available relational database is pretty useful.
