Preach.

This has got to be the most user-blind self-imposed preference in a modern operating system outside of Microsoft's BS.

If you're going to use an OSS operating system, the control of what is placed on the system should be inherently with the user. If the developer has a question if a new package should be added or is required, throw a prompt and ask -- with a default to not use application containers and the default packaging system.

Really not hard.
