I don't see any reason for the excitement myself.

personally I don't think gravity has waves , there may have
been a wave generated for some undisclosed reason , but I
have always considered that gravity has a field and does not
travel much like a magnetic field.

its field may be increased or decreased by the amount of mass that makes up the field , so at that point of increase or decrease of mass the field intensity would move outwards or inwards but it shouldn't move like a wave moves.

more like a intensity increase or decrease at any given point
along the radius of the field.
