But your argument only holds for a *specific* size, as all other sizes are obtained by scaling that specific size. So, what is the rationale of having 16x16 instead of 18x18 if both are going to be scaled down from the 22x22 size?
This is only because the support for 16x16 icons is not yet implemented. The plan is to include multiple icons sizes in the future based on standard sizes.
