Backporting is a sweet way for us to enjoy the hot new things in the Open Source world without compromising stability like running a development/CVS/snapshot release.
Backporting can be a major PITA if not done correctly! There are lots of compatibility issues that stem from poorly or recklessly done backports.
Developers know what they're talking about, and what they're doing. Nobody's voice is being ignored. Most backports are just a handful of commands (just a few minutes of interactive work), so there is not much effort in the actual backporting process. So if a developer doesn't backport a certain package, it's been done with good reason.
