Bugs get fixed when systems are iterated on. They also tend to be single results from single mistakes, not compound end results of the implementation.

Design features tend to persist.

The phrase/idiom "the purpose of a system is what it does" maps best to situations where a multiple decisions within a system make little sense when viewed through the lens of the stated purpose, but make perfect sense if the actual outcome is the desired one.

It is an invitation to analyze a system while suspending the assumption of good faith on the part of the implementors.

It’s not that simple. Especially not in politics but even in the domain you’re referencing, have you ever seen Mozilla’s bug tracker? Once your project is so big and involves so many people you move beyond fixing everything you want.

There may be central planning at play, in this case I assume there is, but to claim it necessarily is relies on an oversimplification that doesn’t exist in human political machines that are a giant ship of theseus essentially. There’s no identity -> management capacity proven anywhere enough to make that kind of claim. Institutions inherit and have emergent behavior driven by the dynamics of their constituents/individuals. That includes the inability to create imagined outcomes reliably. The platonic intent and physical regimes cannot be integrated.
