It is a non event in Cessnas.
Back when Paul Hardy (RIP) was teaching me glide approaches pre first solo and later practicing enroute engine failures/forced landings, he taught me to use flap 'like a throttle'. Thoughtfull use of flap on final approach on PFLs was extremely interesting and allowed you to move your aim point back and forth to a limited extent (obviously). Going from flaps 20 back to flaps 10, for instance...or even back to clean...could be used to fine tune your aiming point if falling a little short...and then reselect more flap as desired later in the approach or just prior to the landing flare.
Part of the Roberston Stol kit on many Missionary C206s in PNG was a big red button on the control column...that dumped flaps rapidly from whatever they were selected to back to zero. It worked well...really well.
That doesn't mean you can dump the flaps in the flare and then sit there thumb in bum - mind in neutral...it does take a modest amount of skill and forethought.
