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.
