Well, Mycom and Russian devs do that all the time, except its "ok, we deploy tomorrow'
"Nyat, we find many, many new bugs, need new week to fix them!"
*release delayed 2 1/2 more weeks*
every patch...
I mean, I could envision a world where that is possible.
But that is not the world of western software development, where schedules are so tight, everything is modeled around optimal exposure & deployment itself involves such high stakes.
