I thought about this: we ship a small bundle with our additional things and 
add that on the fly to the system bundle. I wonder if any of those roots are 
really needed these days anymore?

Yes, that is exactly what I had in mind with my original post.

As a user I must be able to add my own roots for me without losing the global 
store. So if I decide that I trust CA X and my admin does not it's totally 
legal that I can import them and don't get warnings about those certs and 
other users do.
