I am designing a PCB with somewhat limited space. To save space, I am placing some vias on component pads. However, I am not sure if this is a good practice in PCB design. As far as I understand, there are certain pros and cons for such designs.

My layout contains vias that are directly placed on pads or at least intersect them (see example below, courtesy of Eurocircuits):

However, it seems like big PCB houses (e.g. Eurocircuits) will offer plugging/filling of vias, eliminating the wicking concern. This makes the production more costly.

If the cost argument is not considered, what is the reason to use or not to use vias on component pads?
