So if you can reasonably see that there is no immediate traffic, you don't have to wait at an intersection and risk hoping that another driver at a 4 way stop will respect the stop sign. This whole law is being called the "Colorado Safety Stop" but was initially called an Idaho stop [1][2]. It resulted in a 23% reduction in bicycle crashes in intersections with STOP signs only [3].
Even if you think the results are not intuitive, they are certainly backed by data. Making this a law just means cyclists won't be harassed by law enforcement for doing what is statistically known to be safer.

If restricted visibility does not allow you to assess whether the intersection is clear - stopping always is also the right thing to do.
