No, in fact, it often decreases the load on the router (especially if fragmentation is avoided).

BTW, mss-adjust shouldn't be needed for the network to transfer data, it's a optimization feature.  If it is needed, there's an issue with PMTUD.

If used appropriately, don't see a reason why you wouldn't want to use it.
