  In this note, we compute the Gelfand-Kirillov dimension of cosemisimple Hopf
algebras that arise as deformations of a linearly reductive algebraic group.
Our work lies in a purely algebraic setting and generalizes results of
Goodearl-Zhang (2007), of Banica-Vergnioux (2009), and of
D'Andrea-Pinzari-Rossi (2017).
