I think it's relevant to point out that originally some scenes had lower values for corruption checks, meaning that it was easier to be locked out of some choices, Amber and Mom hug in this case. However the values were increased later, so effectively it became less punishing to make corruption runs as long as you don't strive for all possible corruption points.
My save has a single corruption point (Bailey) but i think we won't need such low values at all even in 1.0 since WW is making the checks "easier".
In short you can get some corruption if you want and still get all content.
