Do I assume right that the modules shall not be deleted on update? If that is right, I have to add them to the list of exceptions in the build/deleted_file_check.php after this PR will be merged.

[chmst]

Te modules are not deleted on update. Users who have these modules and overrides should not be affected until J8

I am massively against this. It's removing something that has not been deprecated for zero benefit

[chmst]

We don't remove anything for existing applications. Just don't deliver old modules for new installations.

[chmst]

The benefit for NEW applications: Old artilce modules are no longer available. When a user wants to make a module with articles, he can select only the new mod_article where we have all features from the old articles.
This saves us a lot of files (lines of code) which are not at all DRY.
Old applications are not affected and wll work as usual until J8.

[brianteeman]

So it's ok to completely ignore our policies on deprecation etc?

[chmst]

I am adding deprecations right now. This is a draft and work in progress.

It needs also to remove the system tests, e.g. https://github.com/joomla/joomla-cms/tree/6.0-dev/tests/System/integration/site/modules/mod_articles_archive . Currently they are still running in Drone for this PR, and of course they are failing now as the modules are not available in a new installation.
