There already was a discussion on that matter some time ago:

I still think the extended syntax is worth keeping, but it would not be an
enormous problem if it is removed IMO. I never made a speed comparison
between extended slope pattern and the average-pigment_pattern construct,
but it probably will be slower at least to some extend. Since the pattern
is often used for texturing (isosurface) landscapes, speed might be quite
an important argument.
