Motivation

As my understanding.

If we are downloading Google product as a Windows installer, it returns long and encoded URL as https://dl.google.com/tag/s/appguid%3D%7~iid%3D%.
The iid is the "Instance ID", so downloading from this URL twice, the installer will not work. Even if you got the binary...!
As far as I know, they does not open the list of these actual URLs.

I didn't know their motivation, but this is a blocker of getting installer permalinks. Especially in winget-pkgs.
