System FilePath, NIOFileSystem FilePath, and Sendable

I am currently transitioning to using the APIs in NIOFileSystem, but noticed that FilePath is different to the one you import with System. This version does not appear to be Sendable, so I have to keep converting them back to this type from String. Is there an actual difference between these two and are there plans to make them conform to Sendable? I was thinking of extending them in the meantime.

I reuse some models between my front end and backend, so I was hoping to maintain the same type.
