"probably a couple of kb" Pointers are everywhere. In real world applications we see an increase between a quarter to a third. For example in 2016 Mozilla reported 25% increase from 32-bit Firefox to 64-bit [1]. Google deemed it necessary to implement pointer compression in Chrome to counter the effect. Java also has pointer compression.
