when defining a service with a DefinitionDecorator (parent="acme_demo.foo" in XML), the scope is not inherited, which causes issues if the parent definition defines the scope as request and a dependency on the request. Currently, the dependency will be inherited but not the scope, causing a ScopeWideningInjectionException if you don't redeclare the request scope on the child service.

Yes, this is intended behavior. Scopes must be explicitly declared for all services.

why forcing to redeclare it explicitly whereas all other properties are inherited ?

There are a few special properties which are not inherited, see the pass that does it.

Anyway, changing it would create a BC break that we do not really need.
