Removing marker track should ALSO remove markers

When I remove the marker track, the project still functions as if the markers were still there. This would make sense if I was just HIDING the marker track, but I want to get rid of it altogether.
Also, why is it not possible to create more than one version of the marker track?
Please consider these ideas in a future update of Pro 10.
