Certainly this will depend on the application.

I'm not sure that's warranted - according to the table in the source, this will generate covered regions of about 1.25x the shape itself, and shape testing is expensive. If your shapes are distributed widely the trade-off may be different. Note that 50 is the maximum cell covering - it will only have any effect for complex shapes.
We plan on better exposing this knob, however, see linked ticket.
