This limit is configured by individual manufacturers. It depends on the CPU speed and memory. Software improvements will also allow us to push it higher - but those did not filter down into devices yet. Going forward, I expect this limit won't be of much practical importance.
However, breaking content into chapters if content has logical breaking points is always going to work better - no matter how high the limit is.
