Depends on the gooseneck fitting. Mine is a sliding gooseneck that
can be raised or lowered at will. Oftentimes the gooseneck will
fit an internal track in the mast and although it may have been
riveted on to begin with it is a simple matter to drill out the rivets
and change the location while adding new rivets. This would leave
holes in the mast to show that it was done, however.

I believe the gooseneck was riveted to the mast on this vessel when originally manufactured

More likely is a mainsail cut to lower the boom on the aft end
by increasing the length of the leech on the mainsail. This would
result in the aft end of the boom being lower than the forward
end. The original sail held the boom horizontal, I'm sure.

What sort of racing allows modifcation of the main so as to increase area beyond the manufactures specifications?
