electronic devices that use ceramic smd capacitors stored for years and indefinitely without use do these ceramic smd capacitors change their values, lose capacitance and die?
This is just one maker, different brands will have differences.
Also these are all safety margins and more or less theoretical.
Soldered SMD caps are generally pretty resilient, at least they don't leak destroying other components, so that's a plus. https://page.venkel.com/hubfs/1_Ima...and-shelf-life-mlcc-components-venkel-ltd.pdf
