I don't understand why someone would wrap an untrusted application with their own code vs using something like Systemd's exec capabilities to do the same without having to have a binary wrapper. What benefits do you see over the systemd solution?
Systemd's exec capabilities are great, but don't allow the application developer to dynamically restrict access rights to resources. So you could restrict a text editor for instance to the file it was launched to edit, instead of a hardcoded directory.
