Patching modules from D8 to D9

Currently there's an interesting obstacle to working with Drupal 9: if a D8 module doesn't yet have D9 support, and a patch is sitting in the issue queue, cweagans/composer-patches can't handle the scenario ... because the composer dependency tree prevents the module version being installed installed. What can you do?

The last option looks like this:

Add a package entry specifically for this Drupal module to your composer.json:

    "type": "package",
    "package": {
        "name": "drupal/cache_control_override",
        "type": "drupal-module",
        "version": "1.0.0",
        "source": {
            "type": "git",
            "url": "",
            "reference": "8db91684a427366d8f9c51f60cbac10c2d586d95"

We've used a Git SHA so Composer won't bother with version specifics, and the presence of the package entry means we won't look this up in
