So apparently this might be turned into a Disney+ limited tv series instead:

Probably good to be wary of the rumor as there are a lot of rumors around SW tv shows right now.
I would be open for it, as I always saw the idea of an Obi-Wan movie to be something much more character focused and not some big epic, and TV series would be perfect for that.
