Note that there are two directions we can go in here. We've been talking (for awhile) about using Web Share Target to be able to receive blobs, filtering by MIME type. A recent discussion [1] on TAG review considered a redesign of the API to make accepting and filtering by MIME type more natural. We could simply use Web Share Target here for opening files on the web, but it would likely be a one-way relationship (open-and-upload or open-and-view) rather than two-way (open-edit-and-write-back). Extending it to a two-way relationship would likely feel like a hack.

The other direction is to just invent a new API, similar to Ballista as originally proposed in 2015 [2].
