Can't test Composer-changing core patches
It seems like patches for composer.json and composer.lock don't apply, probably because Drush is added during lando rebuild ... See for example Export configuration YAML strings as multiline where the patch from #64 doesn't apply.
Is it possible to somehow squeeze in application of patches such as this during install, before Drush is installed, with an extra parameter, like lando rebuild -y patch https://www.drupal.org/files/issues/2021-02-05/2844452-64.patch?
... or perhaps drupal-contributions can check if a patch file is present, and if yes apply it during lando rebuild -y before, Drush is installed?
A patch like Add new “Content Editor” role to Standard Profile (latest: #24) is also difficult to test, since the patch needs to be applied prior to installation.
