Current spec is not friendly for massive points.

[insar-dev]

I have massive points that almost fill the tile.
So the coordinate data takes the major size of tile.
Would the spec design new format for this situation?
For example, supposing the extent is 4096, it can use 4096 * 4096 bit matrix to store x and y.
if( bit(x, y) == 1), it has coordinate, else.....
And we can use array to store properties(number value?)., then compress them like being done in 3d tiles.
