I'm not sold on this yet. Can't people run update on shelve by themselve?
In all cases, It should probably live has a third party extension for a
while and see if it get traction there.

doing the right thing and we should rely on it, or shelve is doing
something wrong and we should fix it.

You need locking, but I'm not sure why you need transaction here, you
are not adding anything to the store, are you? It seems like you are
just changing the working copy parent and content.
