The "install as needed" linters of course should live in their own separate universe, not scattered everywhere.
Alternatively you ask people to install linters themselves, and refuse to run if they're outdated. Language X devs likely already have reasonably up-to-date language X linters installed, or know how to install them anyway.
A lot of effort: probably. Many different platforms: there are three platforms that carry any weight. See GitHub Actions runner environments.
Docker on the dev machines is easy for the project, but (1) performance is subpar on macOS and Windows due to virtualization; (2) it also gets outdated; (3) the image is easily gone if you like pruning, then you need to
pull the image all over again. (Thankfully the image isn't huge, ~380MB at the moment.)
