Kassi,
The Alias format has been on my list for some time, but since we don't keep them in our repository, I have yet to put much effort into it.
I do feel they are important, especially to a pre-ingest workflow. I have come across them a few times where the alias is there, but the original file is not. Opening the Alias file can help me understand where the file original was located and some other details which may help in documentation.
Definitely a worthwhile task. Let me know how I can help.
