The current implementation of 'Exclusive Split' is not actually useful because we always need to set each condition for all the branches.
Imagine, if we have 100 enumeration values and only a few conditions out of the 100 are required for branching, then do we need to set 100 arrows in the microflow?
That's not realistic, especially for readability; too many arrows.
In order to resolve this, the 'Other' condition should be accepted (not showing an error).
