"Edit: it looks like the VE has said 'Save page' instead of 'Publish' for quite a while - it's not related to the above issues. We'll give some thought to whether to make it consistent (and if so, which version should win)."

Good point.

Although this entirely validates two things I've said countless times, first having too many editors leads to a bad user experience, and each of them have their own crazy quirks. In this case a big issue with label consistency. Knowing which editor will show up is largely a guessing game at this point.

Second, the label in the interface is largely irrelevant. Despite using VE, SE, RE, and CE, I hardly ever notice the caption. In some cases the page is saved using keyboard shortcuts and I might not even look at the label at all.

Still, for consistency sake, it might be a good idea to have them like the others or simply wait for the next VE update (if ever).
