Symfony CMF/Routing - remove trailing slash

Question

We run symfony v4.4.3, symfony-cmf 2.1.1 and symfony-cmf/routing-bundle 2.0.0.

We are using the cmf routing to load routes from db.

Symfony 4 should redirect from url with trailing slash to the same url without trailing slash, but it does not happen, trailing slash throws 404.

I started study the code what is happening where and why and I found in generated container router service getter, where is something like this

new DynamicRouter(
    new NestedMatcher(
        new UrlMatcher()
    )
)

UrlMatcher does not redirect if it is not instance of RedirectUrlMatcherInterface, but this base one is not.

So I realized it should be possible to inject RedirectableUrlMatcher to NestedRouter and I tried to find the way how to do it in documentation, but it was unsuccessful. So I took a look into cmf bundle routing extension, but I cant find any possibility to set specified router, or enable redirect.

But then I noticed RedirectableUrlMatcher is deprecated...

How to remove trailing slashes?
