I was just searching through the 3.1 docs and can't find any reference to
the blend_map.  Is it still supported?  If not why was it dropped?

I have never heard of it. Are you sure that it was a feature of Pov and if
so what version ? It might be from a custom version of Pov but not in the
official version.

These are the only map type functions that I can remember that are supported:

bump_map
density_map
image_map
material_map
normal_map
pigment_map
texture_map

OUCH - I don't know how I missed color_map as many times as I have used it.

I forget where I saw it used, but I am certain I saw it somewhere.  It is
used in pigments, and works on them the way slope_map does on normal.  I am
not sure if I saw it in use with an official version, or a patch though.

  I think the closest equivalents would be texture_map and pigment_map. You
can combine an amazing amount of patterns and colors with these two features.

See the Pattern Modifiers section of the docs for a reference to blend_map:

Pattern modifiers

Pattern modifiers are statements or parameters which modify how a pattern
is evaluated or tells what to do with the pattern. The complete syntax is:

PATTERN_MODIFIER:

BLEND_MAP_MODIFIER | AGATE_MODIFIER | DENSITY_FILE_MODIFIER |
QUILTED_MODIFIER | BRICK_MODIFIER |
turbulence <Amount> | octaves Count | omega Amount | lambda Amount |
warp { [WARP_ITEMS...] } |
TRANSFORMATION

BLEND_MAP_MODIFIER:

frequency Amount | phase Amount |
ramp_wave | triangle_wave | sine_wave | scallop_wave |
cubic_wave | poly_wave [Exponent]

The blend_map is the general term for the different maps that take an
index from 0 to 1 and return texturing information of some sort.  The
different kinds of blend maps are listed elsewhere in this thread.

You might have seen blend_map in the POV source code.
