Why did Axial Capacitors Fall Out of Use in the Industry?

Single-sided PCBs frequently required the use of wire links to bridge over other tracks on the board. With a suitable circuit layout, the use of axial capacitors (rather than radial) could be used to allow tracks to cross each other, removing the need to use a separate wire link. Axial resistors offer the same capability, of course.
