I'm also wary to use programming languages as a metaphor to advance a view about writing constitutions.
I can agree with the broad point that inertia is a major cause for constitutions to stay the same over time. But I disagree with the original commenter's implication that more recently-written constitutions tend to be better than older ones due to lessons from the past, because of the idea (perhaps relating to yours) that contemporary political and ideological considerations can introduce weaknesses into more recently-written constitutions, which overlook potential lessons from the past.
