My 1st guess was that they wanted to test the users reactions but it was a bad idea. iWork users and XCode users are probably not the same kind of users. Maybe it's the explanation.
We may assume that XCode users are more aware of computer's behavior than the ones targetted by iWork, TextEdit or Preview.
On one side we have the techies supposed to know what they do.
On the other side, standard users which aren't so deeply aware of the machine's behavior.
No offense here, just remember the old days when we were said that before delivering products to 'standard customers' they passed "monkey tests".
The new OS is designed to bring better safety in case of failure. The collateral effect is that the user must change old workflows able to change the document contents when it's not wanted.
As I wrote several times, I anticipated this behavior years ago. You will have to adapt your workflow too.
Switching to an other operating system would probably be a temporary answer. We may bet that with a gap of three or five years M…oSoft will bring the same change to its system.
I read here rants against Save As… dropping or against Versions but I read elsewhere messages from M…oSoft customers asking when their tools will benefit of the same features.
The grass is always greener on the other side. 😉
