Opening this as the solution to a bunch of other issues.

This to achieve:

• *nix-like behavior for atime/mtime/etc properties (Getters/Setters should update atime & mtime on file.stat #72)
• Virtual directories (Virtual directories #100)
• User-friendly mode property (Consider using stat-mode module for the mode property vinyl-fs#112)
• Construct with always-valid properties (new fs.Stats doesn't do this)
• Flag remote files (isRemote) and avoid path normalization or do URI normalization (Remote paths #127)
• More?
