The most likely result of not running cleanup is wasted disk space.

The second most likely result is resurrecting deleted data if you do a second 
range movement (expansion, shrink, etc). 

If this is bad for you, you should run cleanup now. For many use cases, it’s a 
nonissue. 

If you know you’re going to add more hosts, be very sure you run cleanup before 
you do so. 

There’s no harm in running cleanup now.
