I would like to know a little more about what this feature will be about.

For the record, the database is on hold without a deadline, so do not expect any news on this matter.

So it can be said that it has been cancelled? It's a pity the images that were shared on the private channels were really interesting

Maybe? or maybe not. As a last effort the codebase has been transferred to our friends at @brickdb , so it's up to them now.
