I find it extremely powerful that major open source projects are calling the shots instead of the major browser vendors.
For some who may not recall, I think the most famous / historic move was when jQuery decided version 2 would deprecate support for IE 6/7/8.
Originally jQuery project would go out of their way to make sure all browsers were covered. Needless to say these days Microsoft is far more receptive to the needs of the open source community.
I apologize for not being more clear. I was thinking about the flexbox more than the IE9 deprecation. The jQuery story was only to reinforce the idea that open source projects are "at the negotiating table".
I don't think this shows the open source projects calling the shots, If anything my experience with jQuery since v2, was that we would use v1 instead of v2 in order to support IE.
Also when you consider how many changes were synced back to v1, I think it shows that at the end of the day, the user calls the shots.
