  The adiabatic hydrodynamization framework is a promising framework within
which to describe and characterize pre-hydrodynamic attractors in a
model-independent fashion. Using this framework, we define a procedure to
identify a time-dependent change in coordinates which reveals a dynamical
reduction in the number of active degrees of freedom. Applying this procedure
to the kinetic theory of a Bjorken-expanding gas of gluons in the small angle
elastic scattering limit, we are able to intuitively explain the self-similar
evolution of the gluon distribution function long before the applicability of
hydrodynamics, as well as the loss of memory of its initial condition.
