<copyright>element indicating that there is no copyright and the software is dedicated to the public domain or should the
<copyright>element just be ommitted?
I'm edited the original extension to include this dependency (KB2919355). This means packages which depend on this extension will need exempt right?
Yes that is likely.
I was trying to say if there is another, maybe better way, I would go for that, in which Verification exempt is not required.
Okay, Got it. Unfortunately at the moment there is not. The reason is that we support back to Windows 7 / PS 2 so we test on a system that has no updates installed so we can make sure that we don't miss any required for a package. Once Windows Server 2008 is no longer supported on Azure this will likely change.
There many not be many users needing them. There are several Nvidia GPU packages available.
As I suggested previously, create one if you need it. You can get help here or in the docs. The Chocolatey Community Repository is maintained by the community. The Community Maintainers are all volunteers and create packages they perhaps need or others have requested. Pick up the one that was mentioned above and be part of the community.
I hoped that after so long there will be some progress
There hasn't, there are too many issues that needs to be resolved before one can be created (from my point of view).
I have actually been wanting to create one since 2016, but due to the already mentioned issues and other that I just don't remember right now I have never been able to produce one that would be reliable enough.
I counted on "choco" as a full replacement for Windows installer
choco isn't a replacement for windows installer. Typically a chocolatey package is a small wrapper around existing installers (or archives) that provides easier installation and upgrades silently.
