I think that was true a few years ago, but I'm not convinced that still 
holds. We currently have a third of the changes volume we had back in 
2015, so a one-year release in 2022 would contain far less changes than 
a 6-month release from 2015.

Also, thanks to our testing and our focus on stability, the pain linked 
to the amount of breaking changes in a release is now negligible 
compared to the basic pain of going through a 1M-core deployment and 
upgrading the various pieces... every 6 months. I've heard of multiple 
users claiming it takes them close to 6 months to upgrade their massive 
deployments to a new version. So when they are done, they have to start
