Premise

As an editor, I would like to be able to download a copy of my vault, so that I can edit it locally on Obsidian.

Implementation

A new project should be created (Name TBA), to keep the core implementation focused on the essentials.
An extension method, extending from IVault, should provide the implementing party with a Blob/Buffer output, containing the full Obisidian vault.
Export method(s?) should provide GZIP / BZIP compressions.
