Well, F. W. Nietzsche never had kids, but I don't think the surname is
extinct. I'm aware of multiple people with the surname Pietschmann. There is
also a common practice of using a first initial and surname as a username and
many Germanic surnames starting with sch[mlr], so I expect that 5 consonants
in an email address local-part where 'sch' are the middle 3 characters are
quite common.
Although not used currently I had formerly such an assigned accountname
(jschleus). Since I think the avoiding of FPs should take priority over
that of FNs I "vote" for the omitting "s".
Maybe it would be a "compromise" to add another regex with at least the
"s" included but 6 required consonants like
[bcdfgjklmnpqrstvwxz]{6}
