Variants are supposed to have descriptions, it is good practice to
explicit in the description if a variant is a default or no. So 'port
variants gizmo' should inform you. I don't remember if the absence of a
description is considered a bug, but it is always possible to file a RFE
for cyrus-sasl2 for the addition of a description for variants.
