Giggi, as you might know there are people who have lots of 2010+ clubs content complete (including WC2018) and people who are ready to help. Just as 2005-10, it won't hurt those who like it very classic but add variety to anyone's liking.
Also, people developing the 2010+ content will face problems with IDs and DB every time a new version of CP is released, so it only creares hurdles for them.
I propose that the content already created by volunteers be included in the next releases. I don't think it will hurt to have help and interest in developing the patch, will it?
E.g. remember when I told you about Gonzaga's new Da Luz stadium, here I made a 2014 UCL dressing for it
