Well, but that less ugly I would say. Also, most people I think agree on
that bus-wide runtime-changable env blocks that are passed to services
are ugly anyway. While we might not outright deprecate this right-yet we
might want to do this eventually.

They way I see this is that the env block stuff is a hint for the
classic activator code, but not more.
