Possible reasons (I don't know which apply here and which are actually
true):

  * When blender was first packaged, that configuration flag did not
    exist.
  * Likewise, but the 'alembic' package was not yet packaged in Guix.
  * The original package author did not notice the WITH_ALEMBIC option.
  * The original package author noticed the option but didn't need
    'alembic' and kept things simple for now.
  * 'alembic' has a large closure size

You'll have to add alembic to the 'inputs' of blender and add
WITH_ALEMBIC to the #:configure-flags of 'blender'.  I don't expect
any problems but hard to tell in advance.
