It can be useful
A little before Covid I used to commute frequently via a well known UK regional airline. On a few occasions I was able to see that the last flight home was going to be very late, especially when it diverted to another airport on the way to us. At least I was able to phone my lift at the destination and ask them to delay by an hour! Clearly there is a chance that another aircraft will be used, but the chance of this happening with little delay (from experience) is limited.
