Yeah 100%. Emacs is almost 50 years old and still very popular. You can't beat it on programming power. Personally, I am not an emacs person (I'm even more notion than obsidian), so I understand your selective, design first approach to this.

IMO
1. Obsidian Dataview should have been editable by design (not to say batch-editable)
2. Obsidian creators should have leveraged their dynalist (outlining) heritage into their newer product.
Your project is still young of course (I like it so far !) but some features are better kept in mind from the start. I hope you will take the best of both world (= see my "block level querying" remark in previous post)
Good luck!
