Part of it might be that I'm often having similar arguments with the team I run about introducing dependencies.

Engineers have a tendency to want to use the perfect tool for a job at the expense of other concerns. It could be ease of maintenance, availability of the skill-set, user experience, or whatever. If there's pushback it's normally that they are putting their own priorities above other people's equally valid concerns.

Often I'm telling people to step-back. Stop pushing, listen to the resistance and learn from it. Maybe I'm on a bit of a crusade when I see similar situations in open-source.
