Also they are being added as deprecated aliases, suggesting they might be removed at some point in the future again?

The main motivation for this was just a shorter spelling. Ok, it seems like there is some trade off... so let's hold off this change for now until we either get more input that shows some clear benefit or shows that there is none and then we can abandon the change.
