| * Fallbacks REST Client FQN to Simple Name and quoted config keys to unquoted | ||
| * <p> | ||
| * Ideally, this shouldn't be required. The old custom implementation allowed us to mix both FQN and Simple Name in a | ||
| * merged configuration to use in the REST Client. The standard Config system does not support such a feature. If a | ||
| * configuration supports multiple names, the user has to use the same name across all configuration sources. No other | ||
| * Quarkus extension behaves this way because only the REST Client extension provides the custom code to make it work. | ||
| * <p> | ||
| * In the case of {@link RegisterRestClient#configKey()}, users either use quoted or unquoted configuration names for | ||
| * single config key segments. Again, the Config system does not support such a feature (but could be implemented), so | ||
| * the interceptor also fallbacks to unquoted configuration names, due to the <code>force</code> property added by | ||
| * {@link AbstractRestClientConfigBuilder#configBuilder(SmallRyeConfigBuilder)}. | ||
