When we designed the RenderingContext functionality to add "arbitrary" objects to RenderingContext (like a Request) in a recent minor release, we tried start making RenderingContext immutable and added the implementation using a "with'er". This is in general a good idea: RenderinContext *should* be immutable. It is however problematic to do this with this single property: It leads to too many and partially breaking changes when consumers try to use this. As such, the patch rolls back to a setAttribute() approach. With the default implementation being done in the Fluid delivered RenderingContext, this change is currently not considered breaking since no (known) consumer actually uses it. To make RenderingContext immutable, we need a new approach, maybe re-starting with a new class that does it. This is a topic for a different major version, though.
