In his blog, Lars puts words on my feelings of weariness in these situations where we are asked much efforts to make our packages modifiable by contributors who can not or want not to use Git.
Most of the core Debian tools, dpkg, debhelper, litnian, debian-installer and many others are developed in Git repositories. Somebody serious about contributing to Debian can hardly avoid Git.
It is time for our tools and methods to evolve and take advantage of Git. This requires to say “no thank you” to contributions based on source packages downloaded from our FTP server, instead of being cloned from the Git repository where the package is actually developed, and this calls the question of what is the real source of the binary packages, but this is a question that is becoming unavoidable.
