Some observations:
* macOS has a new release every year in June[1]
* updates cease after three years[1]
* thus three releases are in support (by that definition) at a time
* we need an image on Cirrus; 13 appeared ~1 month later[2]
* we need Homebrew support; 13 appeared ~3 months later[3]
* we have 13 and 12 in the buildfarm, but no 11
* it's common for developers but uncommon for servers/deployment
So what should our policy be on when to roll the CI image forward? I
guess around New Year/now (~6 months after release) is a good time and
we should just do it. Anyone got a reason why we should wait? Our
other CI OSes have slower major version release cycles and longer
lives, so it's not quite the same hamster wheel of upgrades.
