Question about sys_path

[deathaxe]

What is the exact function of the following package folder detection heuristic?

Is it still relevant?

May we replace it with corresponding sublime.... API calls?

The heuristic to derive package_dir from Default.sort conflicts with default_package_path filtering somewhat.
