Default linking between SWITCH parameters: why?

Why are the two first parameters in the SWITCH conversion node initially linked. Is there a reason?

PS: I first included this question in a thread with a different main topic, [url]Howto use duplicate layer on object with random origin]. Now I think it deserves its own thread.

I think it is fixed in the latest version: … 599f3fd1a9
Not in production yet.

Thanks, Genete!
