I am ok with such new hooks in 4.5 still.

But I cannot see that working on some of the params because for example
$this->jsFiles is not really used anymore after that hook: a local
variable $jsFiles is.

So you should change the $params to include all the variables that are
really used *after* that postProcessing happens.
