Hello, by lack of knowledge I have no idea about merits of rust compared to any other programming language. Generally speaking my wish as an end user and packager is that providing a new stable release takes priority over any enhancement or addition of new features. Maybe not an issue for Debian, but how many distributions have the resources needed to check and carry hundreds of patches?
