State at bootup is a legitimate trade-off decision though: some states you want to survive a power cycle, others you want to reset, and still others you'd want to have a user-configurable default state. Momentary + indicator makes all of that easy, whereas a mechanical off state with powered reset on bootup (or on shutdown) would be a pretty wild "no expense spared" approach. Momentary + indicator vs mechanical toggle really is more than just penny pinching, it's more like not burning wads of banknotes. And it gets even more clear when you enter the present days and add additional inputs like voice control or defaults associated with a personal keyfob.
