CI should run only on files affected by a PR about concepts

I agree and have found this confusing as I start contributing to the v3 effort again.
I would like to know if the markdown I introduce for Rust documents has issues. Instead I see that multiple other tracks have linting issues and it distracts me focusing on what the Rust track needs.

In general I think global checks are to be preferred unless they take too long. If master is green, a failure must've been introduced in the PR anyway. It's more robust. Some checks that only ran on changed files before ended up failing on master despite being green in the PR.

A mandatory check is strictly better than an optional one: it requires fewer judgment calls.

I agree. Those checks were expected to fail as a temporary annoyance until all tracks created those files (that plan didn't work so well because ignoring the checks lead to more missing files over time 🤷), at which point they were meant to become mandatory.

My practical need has been addressed. I had not realized the master branch had fixes. I do not have a strong opinion here so will defer to @SaschaMann since he maintains the CI.
