Work on this stuff:

Thermal reasons, having enough pins and routabke pads on the board so you can land them from the package, mechanical properties (strong enough not to get squished).

We do what we do because it's the cheapest way that covers the requirements and is still easy to assemble.

We slowly move to smaller pitches, but they're more expensive to deal with, you need more accuracy on your pick and place and the tolerances on your pads and soldermask are smaller.
