So you use header compression on all your links, right? No sense reducing your 1Gbps main uplink to 0.98Gbps. The checksum (removed in v6) is already 5% of each IP packet header. Speaking of headers I take it you're using SLIP instead of Ethernet? And you avoid TLS like the plague? I hope you replaced your 15W LED bulbs with 14.7W bulbs as well - your finance department will thank you. This is asinine.
IPv6 is kind of riddled with these changes for sake of change, which just made things worse.
- removing checksum (no way to know when LSR/L2 transit has broken memory, mangling frames)
UDP and TCP have checksums. Other applications have signature mechanisms to verify the data, e.g. gpg, certificates etc. IPsec exists which also provides such mechanisms if needed.
