Well, Zope moved onwards from PAS to PAU


I doubt that seriously:  I would venture that there are two orders of
magnitude more users of PAS than PAU in production deployments.  PAU was
an attempt to port the PAS to a "component-centric" implementation, but
it lost at least a couple of key features along the way:  most notably,
the ZCA provides no way to control the ordering of the invocation of the
plugins.

The ZCA may have no built-in way to control the ordering, but PAU surely does control the ordering. It keeps an ordered list of plugin names. These plugins can either be contained items in the PAU (like in PAS) or utilities for ICredentialsPlugin or IAuthenticatorPlugin.
