changelists and entry-less tree-conflicts

I've gotten a new lead to this: Changelists!

For Changelists to work as intended, it is absolutely necessary to have a WC
entry for every tree-conflict, because a changelist name is stored in the entry.

If there is no entry, the conflicted item can't be in a changelist.

$ svn st
! C Foo.c
C Bar.c

$ svn changelist baz Bar.c
Path 'Bar.c' is now a member of changelist 'baz'.

$ svn st
! C Foo.c

--- Changelist 'baz':
C Bar.c

$ svn changelist baz Foo.c
svn: warning: 'Foo.c' is not under version control

How important are changelists?
