Advice on sharing Mise config across repos

[joehorsnell]

Does anyone have any advice or suggestions please on sharing Mise config, such as tasks and hooks, across a large number (100's) of repos?

Some examples would be defining a (non-trivial) postinstall command that needs to run whenever a certain tool is installed across any repo. Also being able to define common tasks, such as running code quality/linting checks, code coverage, etc. in one place and "import"/reference them across multiple repos.

I noticed that tasks can reference remote files, eg over http, but the definition of the task itself still needs to be duplicated.

One idea that sprung to mind would be to manage the shared Mise config files in one repo, then use Git subtrees to include them into each repo, but maybe I'm missing something more obvious or easy here?

Linking to #3844, in particular this thread, as Java CA trusting was one of the specific use cases I had in mind.
