Sure, but whether or not I decide to stick with <app> depends on many factors. One of those is "does it do everything I need/want." If the answer is no, then that factors into my decision.

No app is gonna rub your back at night or hold your hand on your deathbed (well, yet, google is probably working on something), so "everything" isn't... really a thing.

Who said "everything"? You're just making up arguments I never made. Can we agree that an app with zero features is useless? Assuming we can, the utility of an application is a function of which features it has and how well those features are implemented. So the features are important, and how they're implemented is also important. I don't understand why that's (apparently) controversial.
