Weakness of the small sensor is high(er) ISO thanks to small photocells so if you don't need it, it is better not to use it (other thing is when you want to use it for some kind of concept).

No; other sensors get less noise per unit of sensor area with higher pixel density. In fact, the sensor in prototype in a lab with the least read noise approaching zero (much better than the top end Sony and Nikon High-ISO camera per unit of sensor area) has cell-phone-sized pixels about 1 micron.

It is often easier to blame the size of the pixels instead of the size of sensor, or some compromise due to something like a first-generation fast electronic shutter. A 1" sensor at ISO 3200 should have roughly (generically) the same noise as a FF sensor at ISO 23,328, even if the two sensors had the same size pixels with a 3MP 1" sensor and a 22MP FF sensor.
