I'd subsume this under "ids will grow faster". 

But I would actually see that as an advantage: 

* All your ids have the same type, so either 32 bit is enough for
  everything or you use 64 bit (do the latter if in doubt).
* You only have to monitor a single sequence to see if you are close to
  an overflow, not dozens of them.
* You will probably be more aware that this might be a problem.
