How many of us would be happy working at a software company with a bug tracker from the 90s, artifact management done with FTP, little to no tooling to manage large changes and do code review, no standards around source control, etc.? Those are symptoms of a software development culture stuck in the past.
It would be pretty frustrating to go home from my day job, where we have a much better development workflow, and try to make a contribution to the Debian project using Debian's tools and processes. And I'm sure I'm not the only software engineer who would feel that way. That can become a real problem for the future of Debian if it's not addressed.
