I agree that getting a suitable default from the container would be a good idea. It probably requires cooperation from the many different containers out there, though. There might sometimes be more than one process per container, too, which implies some kind of flexbox-like layout algorithm to allocate memory within the container.

And on the other hand, it's a simple flag. They added one memory flag in over a decade. I think they're holding the line on complexity pretty well?
