I've looked into it again, why this was done. And it is for example
impossible to use an .lrs file without the lResources unit. Now this is
not needed anymore so this might have solved the problem.

Well, without the .lrs files I still have one problem when I omit
lResources from the project. I always get an exception 'resource not
found' for every datamodule, webmodule or webpage in an application. But
thereafter it works. I discovered that this is in debug-mode only. The
exception is catched in a try-except block.
