This is an endless 'holy war'...
I really hope that all those who create web applications test them at the same time when the new beta of the next browser is released and immediately fix all problems before the first user of their applications report this problem to them. (Corrections in the used libraries are even not considered as they are assumed by default...)
The only thing that wonders me, is why all other manufacturers do not use this creative approach of automated and unattended change of the entity in use at the first chance?
Wouldn't all, say, drivers be happy if any time when they stop at the gas station, the manufacturers grab his/her car and install new, improved and more secure and functional (from their point of view) parts that they produced since his/her last stop? More rapid braking, changed behavior of gear-box, new sequence of button presses to unlock the immobilizer or turn on the lights... And, I believe that you don't expect that been agile, all manufacturers will bother themselves to notify all other ones that they must provide compatibility of their parts with the ones that the given manufacturer has improved, do you?
