~/.local/share is set for what? And can I ignore it at backups?

I wonder if ~/.local/share contain real user data or if it only contain session-related data and binary generated stuffs. I also wonder if I can include it in an --ignore statement with [BorgBackup](https://www.borgbackup.org/) cause it really seams to not contain data or config files. Just some kind of cache. So can I just ignore this directory and expect a pretty good recovery, or could it contain some real user-related data?
