I will review the galaxy code more closely and implement it as you suggested.
It's been a while since I've implemented this 'fix', so I will have to dig up
the code that tries to delete the file after upload.
Once it's simple and clean, I will do a pull request.
Thanks for your input.

Subject: Re: [galaxy-dev] Uploading files to galaxy from a folder
Thanks for taking the time to describe your problem and share your
solution - I am sure other institutions have desires to harness the
ftp upload option the way you are doing it.
Is the only problem that occurs if the ownership is incorrect that
Galaxy cannot delete the files? If so - I feel like as a deployer I
would prefer to have a sudo script that just deletes the files instead
of changing the ownership? It is a more... focused sudo command.
This strategy could also allow a slightly more general
universe_wsgi.ini option - say a few options such as:
ftp_upload_delete_handling = __default__ # just assume ownership and delete
ftp_upload_delete_handling = __none__ # don't delete files - user is responsible
ftp_upload_delete_handling = sudo -E rm # command prefix to delete file
I am not saying if you clean up what you have and opened a pull
request I would say no - I am just saying I would be more eager for
this more general option. If you can confirm the only reason the
permissions need to change is to delete the files and likewise prefer
this variant but cannot figure out how to modify upload.py - let me
know I can try to look into it (no promises that it is easy to
