We need to check if maintainers are still up to their task (or lost interest, changed companies, died, ...).

To this end, create some tool to automate it: figure out maintainers from MAINTAINERS, send them a personalized email that lists the parts they're registered for and ask them to check in on a website where they can confirm (or rescind) maintainership. From there, generate a CL to adapt MAINTAINERS appropriately (and do so automatically after a certain time with no response).

Could also send a report to the list about parts of the tree that are still missing maintainers, although that's more complex (requires comparing the MAINTAINERS file with the tree)
