This makes it easier to filter them out when looking for wayward
patches. Right now the list of 15 oldest reviews includes at least 5
WIP patches that weren't marked as such in Gerrit.
For anyone who's not aware, to mark a patch WIP in Gerrit you set
Workflow -1 on it. Anyone can do that to their own patches, and I
believe cores can do it to any patch (but I'd rather not because then I
end up subscribed :-).
