I see here

openapi-model/lib/OpenAPI/Model/Element.pm6

Line 236 in 97d4339

$keys .= grep({ not .key.starts-with('x-') });

that they are ignored, is there any plan to provide support for them ?
may be

"x-github": {
          "enabledForGitHubApps": true,
          "githubCloudOnly": true,
          "previews": [

          ],
          "category": "enterprise-admin",
          "subcategory": "scim"
        }

my $extensions = $operation.extensions; # List of `Pair`s maybe ?
my $github-ext = $extensions.grep(*.key eq 'x-github')
