I'd disagree in the case of gschem. During schematic capture, the main 
purpose of the grid is to make sure, pins and nets actually connect. In 
this context any net that is not a multiple of a certain base is bound to 
make life difficult. 

A grid which is some integer times the base net can be an annoyance, too. 
Just like Stefan mentioned a few postings above: A resistor with pins 900 
units apart does not mix well with a 200 units grid.

That said, there may be a compromise. A coarser dynamic grid might be just 
suggestive rather than enforced. Symbols and nets may prefer to align with 
the coarse net if no other constraint suggests off grid positioning. E.g, 
if there is an active pin end near by, a net might decide to go off the 
coarse grid.

When done right, such a heuristic may result in a smooth user experience 
and nicely aligned symbols. But it would be easy to make it more annoying 
than the current dumb static grid.
