Your arguments seems like: "we can't fix bugs or improve anything because this would break backward compatibility". If the described behavior should be important on many common cases, create a new function. Or new release, deprecated uses for some functions.

Or maybe, add a new argument that allows the user to choose the old or new behavior. The default of this argument might be based on compilation flag or environment variable (this should be possible on all OSes).

But just discarding changes like this, doesn't evolve anything.
