Hello webkit-dev,

We would like to get an official position on AccessHandles (https://github.com/WICG/file-system-access/blob/main/AccessHandle.md), an extension to the Origin Private File System that brings very performant access to data. This new surface differs from existing ones by offering in-place and exclusive write access to a file’s content. This change, along with the ability to consistently read unflushed modifications and the availability of a synchronous variant on dedicated workers, significantly improves performance and unblocks new use cases for the File System Access API.

We had requested a position on a previous iteration of this API: https://lists.webkit.org/pipermail/webkit-dev/2021-February/031689.html. This new proposal is a response to feedback that Storage Foundation seemed to duplicate existing functionality and should be integrated into the File System Access API.

Thank you,
Emanuel Krivoy
