Interesting.....deserving of an RFE maybe. Doesn't immediately look like there is an option to get the same outcome on the new 2.0 node itself.
A workaround/chore to get the same result is using an edit sop to straighten selection of the edges after the fact. There is also the "edge straighten" node to accept a group which does the same thing more procedurally.
kodra But it still feels very weird that they changed this behavior...
Id definitely file a bug report / RFE on this with your version 1 and version 2 screenshots. It looks more like an unintended change in behaviour to me.
