My question as well. It may be useful for USER_INT extensions to have such information in cache. But for USER it is mostly irrelevant. In any case storing in database does not hurt, so I am neutral on this.

In addition I remember old CGL said that files in tslib/ has tslib_ prefix. The added class is not strictly in tslib/ (it is one directory below) but it may be more consistent to call it  tslib_treelistCacheUpdate instead of tx_cms_treelistCacheUpdate. I do not insist. Just thoughts. I am all in favor of tx_ everywhere but mixing tx_cms_ and tslib_ does not look good.

Patch is big I am looking to the code. Could not find any issues by looking. It should be a big advantage to have it in core!
