Post OOP hook conversion test module cleanup

nicxvan → changed the visibility of the branch 3488051-post-oop-hook to hidden.

That's the last of them until preprocess gets in: 📌 Handle module preprocess functions Active

Only two actionable test modules left without issue, twig_theme_test I'd say is soft postponed on the system.module one as it will conflict with that (we could remove the comment fix from it, then it would not) and views_test_data. I suspect that one will run into some weird edge cases with views module and its dynamically defined theme infos + template_preprocess. I think we can either include that in the template_preprocess issue for views.module or do it in a follow-up of that.

I'd suggest we then mark this as fixed, and maybe open both a D12 and a D13 issue to start collecting the respective BC layers that we can remove in the respective major version including their tests. module_test.module for example has a hook_hook_info () (and a function that's been dead code for many years), so that can go in D12.

I created the issue for views_test_data 📌 Convert views_test_data.module to OOP and remove it Active

We can convert that here and figure out if there is anything weird going on.

Your second paragraph is probably right, but let's think about it for a bit.
