Only if the system is online. While that might be the case for most users, Sony designs their hardware with the consideration that it can be used offline. Considering the unit cost of a PS5, and the fact that backup batteries are already the norm, including one isn't imposing at all and there is very little reason to stop. Inventing software solutions to already solved problems (and ones that don't pass all use-cases) isn't really a path worth going down unless the savings are actually significant.
