Hmmm... I wonder if we even need an alias here any more, now that we are not using a generated name. In the case of a stand-alone endpoint we have beans `foo` (consumer) and `foo.handler` (alias for generated handler bean name `FQCN#n`).

In this context, the handlers don't have a wrapper (aside from the chain itself), so using an alias here means we have `foo` (the chain), 'foo$child,bar` and `foo$child.bar.handler` where the last two reference the same bean.

So, I think we can drop the "....handler" alias here.

WDYT?
