Only saw one thing, rest looks good

Quick question: What's the current state of what Python versions we want to limit our user facing tools and libraries to?
I seem to remember we wanted 3.12 for all services, but 3.9 or 3.10 for the rest, but it's been quite a while and I don't think we ever formally decided.

@mephenor Like you said we haven't formally decided this yet but I've updated the CLI tools to 3.12 in order to be able to install them in the same environment. I believe our goal can be update everything to 3.12.
