No. The purpose of the skolemization is to replace blank nodes by IRIs,
because some systems and applications prefer to do so. The well-known/genid
meachanism is to allow these blank-node-replacements to be recognized and
distinguished from other IRIs. None of this is in any way compulsory or even
recommended: it is simply there as a convenience for those who need it.
