  We prove that finite GK-dimensional pre-Nichols algebras of super and
standard type are quotients of the corresponding distinguished pre-Nichols
algebras, except when the braiding matrix is of type super A and the dimension
of the braided vector space is three. For these two exceptions we explicitly
construct substitutes as braided central extensions of the corresponding
pre-Nichols algebras by a polynomial ring in one variable. Via bosonization
this gives new examples of finite GK-dimensional Hopf algebras.
