Allow users to view locked pages

[MarkE]

I tried searching for an answer to this, to no avail, but I would have thought it should be simple!

I have a user role which does not have page-lock permission, but I want it to be able to view locked pages in the back end (i.e. similar to what you can do with a field - give view only access). How do I do this without giving the user page-lock permission? I have managed to find a work-round, by using the module "RestrictTabView" to prevent the role from seeing the settings tab and then enabling page-lock, but I would have thought there should be a way to do this in "native" ProcessWire.
