In my opinion, grid settings belong to the board. A board with only
through hole components is likely to use only imperial units, boards
with only modern SMD packages will use mostly metric, and others with
new and older SMD packages may need both.

If you switch from working on a board with only large PTH components to
a fine pitch SMD one, the grid used in one is likely not going to be
useful in the other.

Best regards,

Isaac
