Would be interesting if you kept cars for longer than 1 race. Possibly useful for endurance races, however clutch heat is simulating this to the point of what would happen during a track day event. I mean certainly you can wear out your clutch but can that really happen within a few laps? I am under the impression that your clutch would heat up and just constantly slip with minimal wear to the plate. Certainly there would always be some wear even when slipping due to heat, but could you really destroy a racing clutch within a track day. (Or a typical daily driver clutch for that matter).
It could be interesting if this actually can occur in real life. However there would need to be major part replacement if you did the during an event, or be out for good... Hmm yea I am undecided depending on reality!
