To which of all your multiple working copies do you want to push the lock? I'd
say that SVN is right that it connects the lock to both the user and one
specific working copy, otherwise you could commit changes from one of your
WCs that conflict with changes in a different WC.

What SVN should IMHO do is tell you when an operation on a WC would break the
association between a lock and that WC, like the switch seems to have done.
It could even remember the lock and restore it when switching back.
Otherwise, you don't have to use "switch" to create a branch or afterwards,
you can also check out a new WC. Further, it would make sense to lock the
file in both the trunk and the branch, and do both in separate working
copies. Lastly, educating people why they must steal their own lock (bound to
working copy, not just user) should be pretty easy.

No doubt about that, I believe that initially it was seen as wrong approach by
many people but is now recognised as valuable and necessary feature. It's not
a second-class feature.
