The social problem is that maintaining backward compatibility with boring technology is considered harmful by the current Python community. There was an active campaign to extract pledges from popular Python library authors to break compatibility with Python 2 by a certain date. This means that if you are volunteering to maintain what you want kept, you had better not tell anyone about it.
Do you have any URIs or back up links? Encouragement to actively break compatibility sounds like "inciting murder" vs. a more tame "don't expend effort (go to medical school)" to save folks.
{ Oh, and before anyone jumps on me, this is only an analogy as it relates to freshman moral philosophy courses, not an attempt by me to over-dramatize - that is more the fault of said courses trying to engage 18 year olds. :-) I'm mostly interested in the active-passive details of the pledge campaign. }
You can't carry everything to very long term horizons, especially for categories of "everything" whose user base is 2 people and 1 squirrel.
People who want otherwise should volunteer to maintain what they want kept.
