This is weird. Noise reduction software has significantly improved and shots at "stratospheric ISO levels" are now usable, hence it being shown off.
Sounds like you don't shoot in low light conditions.
A) high ISO helps mitigate shallow DOF in low light
B) high ISO helps reduce exposure time in low/no light conditions
When shooting at night 1600-8000 is common.
