How do I inject a runtime bean into a Jersey DynamicFeature in a Quarkus Extension?

Question

I have a Quarkus extension targeting Quarkus 2.16.4.Final which has a DynamicFeature which needs runtime beans to run its configure method. I saw a related question here, where the answer says to use Arc.container().instance(...) to access the bean. However, the bean I need is a runtime bean that depends on a runtime Config from another extension, so it fails at build time with this error. How do I register a DynamicFeature with resteasy-reactive?

DynamicFeature implementation:

package mypackage;

import io.quarkus.arc.Arc;

import javax.ws.rs.container.DynamicFeature;
import javax.ws.rs.container.ResourceInfo;
import javax.ws.rs.core.FeatureContext;
import javax.ws.rs.ext.Provider;

@Provider
public class MyDynamicFeature implements DynamicFeature {

    @Override
    public void configure(ResourceInfo resourceInfo, FeatureContext context) {
        MyAnnotation annot = resourceInfo.getResourceMethod().getAnnotation(MyAnnotation.class);
        if (annot == null) {
            annot = resourceInfo.getResourceClass().getAnnotation(MyAnnotation.class);
        }

        if (annot != null && !annot.enabled()) {
            return;
        }
        String name = someLogicToDeriveName();
        AnnotationConfig config = someLogicToDeriveConfig();

        try (var myBeanHandle =  Arc.container().instance(MyBean.class)) {
            MyBean myBean = myBeanHandle.get();
            context.register(new MyFilter(myBean, config, name));
        }
    }
}

The bean it is accessing has a runtime config dependency.

I've tried to remove the @Provider annotation and expose it as a CDI bean from my extension instead, but then it never actually ends up registering itself as a filter. Is there a programmatic way to do so, or is there an idiomatic way to inject a runtime bean (with runtime config dependencies) into a DynamicFeature annotated with @Provider?
