The offset is used to transform the wire encoding of the packet number, but the connection still uses the same monotonically increasing packet number space (no gaps). This solution requires very little per packet CPU overhead, compared to PNE. Unlike the PNE proposal (#1079), this doesn't fix the ossification/greasing problem as well. Instead, I'd like to treat that as a separate problem (and a separate PR) and attempt to solve that with a non-cryptographic solution (shuffle for instance).
