vim-addons
Joey wonders why vim addons are not enabled by default using the new Debian infrastructure.
For single-user systems, Joey is right: enabling addons by default would be best. But for multi-user systems, I think disabled-by-default is better. Otherwise, installing an add-on would change vim's behavior unexpectedly for all users. (Unlike a daemon, which runs once per system; a vim addon is run by each user, every time they start vim.) This is especially bad because vim users tend to have carefully personalized configurations.
Should the defaults cater to multi-user systems at the expense of single-user ones? Probably not, since admins of large multi-user systems are generally willing and able to figure out how to change their configurations, while many single-user machine owners need something that "just works". Perhaps the default configuration should load all installed addons, but local admins should be able to easily change this to load only addons enabled by the current user.
