The program wouldn't spawn further activity internally,
if there are no packages.

But as an interface it should look like 0 packages is the same as n packages.

Anyway, I was more talking about the human processing.
All the programmers that use pacman, yay, ... ansible.aur
need to put an "if" to check whether their variable is not 0 to avoid an error.
With computer programs we try to take away effort from humans.
