I get the point here but for many organizations and types of companies this is a terrible and unworkable idea. A lot of companies have to wait till weekend for maintenance (e.g. trading/market making apps), and so your only options are deploy on weekend which means weekend work or on friday afternoon/evening. Once week starts there are no good times to do a release. So for a vast number of super critical systems friday is THE day to do a release.

Yes, that means potential weekend work if it goes wrong, and it increases the odds of a bad monday... but both of those can be fixed with good testing/automation.
