Giving us an option to turn on legacy would be counterproductive. There's no point in keeping the outdated software. Because eventually it's going to become so outdated that it won't even be possible to use.

So that's why we need to let the old software go and hang in there while we wait for improvements to be made to the new software. If you think that maintaining the legacy platform is worthwhile then you obviously don't understand half of the full picture as to why legacy must go.
