In addition to the other (correct) answers you've received, this one
also applies: "Because nobody else is using CAST6."

(Also, CAST6 is a different algorithm than CAST5.  It's not really a
"variant".  The algorithms are similar, yes, but then again so are
Blowfish and CAST5-128, and nobody calls Blowfish and CAST5 variants of
one another.)
