Ah, that section is not exposed in the new chrome status UI, sorry it was missing.
Looking at the checklist, we are covered on basic tooling; Autocomplete works as described in "New WebIDL/DOM interfaces and attributes".
As for extended tooling, we'll eventually want to be able to explore files stored in OPFS. There are two tracking bugs related to this: crbug.com/256067
. This API doesn't really add new storage backends, just new ways to interact with files, so we'd be covered by those as well.
