Licat’s answer:
We have no plans to implement Notion/Airtable-like database functionalities, but that in theory doesn’t prevent plugin authors from turning Markdown tables into databases […] This is the trade-off we made for Obsidian, which is why I said I don’t think this would be changed at all. It’s in Obsidian’s DNA. Of course, it’s entirely up to you whether you want to make that trade-off, and we respect that. If you value functionality more than future-proofness, something like Notion or Fibery might work better.
