Why this change in the question page?

Hi,

I downloaded latest commit and found some unexpected changes to the layout of the question page.
(theme/default/question.php)
It now has a left-side region showing the participants, stats and subscribe button.
They do not seem to be optional/configurable.
Why are they at that location when we have the widgets to place them as we like?
Do I have to use another shortcode to have the question page without additional (widget) content and at full width (as asked and agreed here: http://anspress.io/questions/question/2400/layout-of-single-question-page/#comment-8244)
