File System Access API has some serious issues. To quote Mozilla's position on the topic
> There's a subset of this API we're quite enthusiastic about (in particular providing a read/write API for files and directories as alternative storage endpoint), but it is wrapped together with aspects for which we do not think meaningful end user consent is possible to obtain (in particular cross-site access to the end user's local file system). Overall we consider this harmful therefore, but Mozilla could be supportive of parts, provided this were segmented better.
I think most users would probably be better off without this proposal.
It sounds like this would prevent users from backing up their own data, which is hard with localStorage and sessionStorage, and instead having to rely on the site owner.
However this doesn't go into any detail, so maybe they have some convenient way of being able to access these files in mind, but we'll never know. It reminds me of another shallow dismissal by Mozilla: https://github.com/mdn/content/pull/36294 https://webreflection.medium.com/mdn-doesnt-trust-you-should...
