I'm not going to speak for the developers as I imagine they'll chime in soon, but I imagine it's just an early inconvenience during the beta period while they work on getting the underpinnings all sorted. Just wanted to give us something to play with so we don't get too anxious. I take it as just something to deal with for right now like having to click yes on the reload message 3 times after a save. i imagine it won't always be like this as they rearrange and polish up the editor, or I may be wrong entirely.
