My personal "solution" to this is to set up a separate "Junk" application category at the bottom of the list, and move them there.

Those three are a special case, but in the more general sense it would be nice if we could do something about bug 3602 (osso-software-version-rx*4 dependencies prevent removing many unnecessary packages).

One way to deal with it would be to produce osso-software-version-rxXX-minimal packages that depend only on the essentials to boot the device and start the UI. The problem with that is that most of the non-essential apps cannot be installed via the application manager, so we would have to roll separate user-visible metapackages for them. We'll also need some user-friendly way of removing unwanted packages safely, and some way to store the unwanted info so that it persists after restoring a backup (bug 6214).

All of which is a lot of work obviously :- ) Any takers?
