This might be possible yeah, I'll think about it!

Already possible, see images below :)

Don't forget the near clipping plane :)
Thanks for the suggestion though!

I think this may have been fixed in Beta 0.18, which is currently being verified by Unity. Let me know if it works when it's out :)

Could you elaborate?
Delete how?
Remove a reference or delete the Texture2D node?
How does it break?
Does the shader go pink or do you get red inputs on the following nodes?
