partially a joke. I don't see any good and simple rule to restrict the
number of methods.
dot was added as a method a few numpy versions ago, because it is
painful to write nested or sequential dot products. Alan was in favor
of the dot method and of matrix algebra because it's much easier on
new users who come from a background that has a dot product as "*" or
similar operator.
As Skipper, I think the number of methods is not really huge
(especially not numerical operations)
