[Feature Request] What happened to FS3 (FileSystem)?

[laurenyew-nytimes]

Is your feature request related to a problem? Please describe.
We're looking into migrating from Store4 into Store 5. What happened to FS3 (FileSystem)? We were using this regularly for a persistence solution. Is this planning to be added back or was this removed for a particular reason?

Describe the solution you'd like
Documentation on migration path (if FS3 was removed, why, and suggestions on what to replace it with).
If FS3 is going to be added back in, an ETA on that.

Describe alternatives you've considered
We're looking into having to reimplement FS3 on our own, but if it's planning on being added back in, we don't want to duplicate work.

Additional context
N/A

Hey there - Adding FileSystem sounds fine to me. Looking at its dependencies it shouldn't be a huge lift. Happy to put it on our roadmap as long as @digitalbuddha doesn't have any concerns

[digitalbuddha]

No concerns or compat issues. Source of truth API has not changed we just need to add the module again. Pardon the mess. I'll try to get to it early next week

Just keep in mind that the FS3 implementation does not work correct using a non unix filesystem. For example https://github.com/aclassen/Store/blob/main/filesystem-kmp/src/commonMain/kotlin/com/dropbox/kmp/external/fs3/filesystem/FSFile.kt#L27
This is not true for windows , beside other limitations.
@laurenyew-nytimes as long there is no offical one you can also take a look at my fork but it's Store4.
I could also create a pr if needed , i updated it already to Store5

@aclassen We need it for Android only. @digitalbuddha Has FS3 been added into this repo in Store 5?
