I am not sure if it has been discussed in the past, but here's what I have:
- It is a bit complicated to have the installer download something
from the Internet.
- Having the installer connect to a third-party website can cause
security issue and may violate user privacy (IP address).
- It wouldn't work if the system doesn't have an Internet connection.
(Hypothetically it can happen to IT technicians deploying to computers
within an Intranet.)
