Users Relocating Desktop location to Network Share

One of the techs in my organization recently found out that about 10 users at one of our worksites have been changing the target location of their desktop to their personal folders on our network share, instead of leaving it on their local ssd. My fellow tech is really concerned about this. I don't see any immediate harm.

Is this something we need to worry about? Are there negative implications from increased network activity to consider? Any insight would be much appreciated.
