How to efficiently link notes with time-based filenames?

Thanks, this is what I currently do. In the mean time I hope that this relatively popular feature gets implemented in the future: Use H1 or YAML property "title" instead of or in addition to filename as display name.

That’s true and the main reason I haven’t converted the existing notes to what Obsidian works well it. There are considerable risks in my view and don’t want to break things.
