Why do you think it's useful to stick a "post-neoliberal" moniker on them, especially given that Wikipedia seems to think that "neoliberal" is a pejorative term used mostly by people who don't like markets?

As far as I can make out, the "post-" prefix in words such as postneoliberal, postcolonial, postmodern, etc. means not merely "after", but also "in reaction or opposition to", with connotations of supercession of the old and bad by the superior new and good. Claiming the "post-" moniker for oneself is a way of linguistically framing the situation (that is, casting a magic spell) to define oneself into having the high moral ground.
