Comment 15 for bug 458872

"Regression" is very relative. I think in this precise case we can easily anticipate the costs and benefits of such a change without requiring user testing. Few people will complain that CJ doesn't remove this kind of obsolete packages, and if they really know they want to get rid of them, they can use Synaptic. And in general, packages no associated with any repository are few and won't do much harm: the big part is removing libraries you installed automatically as dependencies of other programs, and kernels.

OTC, people that don't understand that these packages may be useful to them will not get bitten if we make this change, which is a *huge* benefit.

There's also another solution: show these packages, but don't check them for removal by default. Not sure that's easy to do.
