Credit to @mcdwayne for this script. It is worth adding. Need to get the Wiki going.

made a new one, thought to myself "why don't we just make a report about all of the modules and just make that report available?"

So I am doing this. Issue is time estimate is like 250ish hours (given~ 2~2.5 minutes per file gen)
Just generated the first 64 in 30 minutes.

This script is SUPER useful, but I don't know that it would be helpful to distribute? I suspect now that a first round of "check all the things" is done, it will be ad-hoc-per-module from hereon?

In my latest PR, I do describe usage for running this against contrib: https://github.com/mglaman/drupal-check/blob/feature/readme/README.md#usage

And in the wiki I explain how to run it: https://github.com/mglaman/drupal-check/wiki/Drupal-9-Readiness#im-a-module-maintainer

If that's in alignment with what you're thinking too this ticket could be closed after the PR is merged.

I think we can close this per @josephdpurcell work on README and Wiki
