In this video ImMagic explains why he prefers to use control groups on buildings, since there will be buildings all over the map and he will only be interested in producing them on buildings in one section of the map.

For those of us who use control groups exclusively on units (especially on hybrid maps that include ships) it is necessary for me to use the hotkeys for each building.
For this reason I request to include the possibility of disabling production on some buildings (this should cancel all ongoing production since it can be abused when reaching the population limit).
