The following configuration generates the following url for example.

tx_awesomeextension_bestplugin[filter][foo] = 1
tx_awesomeextension_bestplugin[filter][bar] = 0

http://great.ddev.site/foo0

routeEnhancers:
    Sample:
        type: Extbase
        extension: AwesomeExtension
        plugin: BestPlugin
        routes:
            -   routePath: '/{foo}{bar}'
                _arguments:
                    foo: 'filter/foo'
                    bar: 'filter/bar'
                _controller: 'Foo::bar'
        defaultController: 'Foo::bar'
        aspects:
            foo:
                type: StaticValueMapper
                map:
                    foo: 1

Go one step further and lets add another StaticValueMapper:

routeEnhancers:
    Sample:
        type: Extbase
        extension: AwesomeExtension
        plugin: BestPlugin
        routes:
            -   routePath: '/{foo}{bar}'
                _arguments:
                    foo: 'filter/foo'
                    bar: 'filter/bar'
                _controller: 'Foo::bar'
        defaultController: 'Foo::bar'
        aspects:
            foo:
                type: StaticValueMapper
                map:
                    foo: 1
            bar:
                type: StaticValueMapper
                map:
                    bar: 1

We would expect to see: http://great.ddev.site/foo?tx_awesomeextension_bestplugin[filter][bar]=0

What actually happens: http://great.ddev.site/10
