Wow, no. I haven't seen a 0.1"-grid-based PCB layout since I was a kid.
I think it also depends on the component packages you like to use.
When you dealing with many BGA components, you like to have an autorouter
which can support 45deg routing on single traces. It'll save on layers, let
alone save your project.
I'm still trying to find out if the gEDA PCB can support this. Plus with
differential signaling very common on FPGA's now, it's nice to have one that
supports 45 deg routing of differential pairs.

My layouts are not particularly dense, and my
grids are typically set to
0.005" or 0.001".
Oops. I was thinking pads here. Really most of the lines need to avoid
pads and via's.
