Of course, I volunteer to participate in this cleaning.

Start by locating the compute drivers and related references for the providers listed in the issue. Check how unavailable services are represented and identify the tests or documentation affected; done means the obsolete drivers are cleaned up consistently without breaking the remaining provider support.
