Just to slightly augment what was already posted by Aaron; deletes are
not special in terms of the chosen consistency level. If you submit a
mutation with a QUOROM consistency level for example, that QUOROM
consistency requirement applies equally to deletes as it does to
inserts.

(That said, deletes are a bit special in other ways to go
GCGraceSeconds, but that is another story.)
