I would like to stay consistent. In one hook we now have ModuleModel $model and Module $module.

So here it should either be PageModel $model and PageRegular $page or PageModel $pageModel and PageRegular $pageRegular.

Ah i know what you mean. i will check all hooks and push it in this PR. My goal is to be consistent too.

Here is an overview with all Contao hooks: https://gist.github.com/Tastaturberuf/8851fc3348dcc229f4a49d81bc9220d0

On first sign i think we should suffix all models with Model to make clear what it is.

e.g.
https://docs.contao.org/dev/reference/hooks/getPageLayout/
https://docs.contao.org/dev/reference/hooks/getFrontendModule/

@Tastaturberuf not sure you'd still be working on this - but: in Contao itself we usually use just $page for a PageModel for example. So I think we should do the same in the docs (I have adjusted the getPageLayout hook accordingly).

Regarding the getFrontendModule case: there I think it makes sense to just use $model and $module as this hook specifically handles modules and thus you only have to distinguish this way.
