If we want to introduce a system wide container in v10,
the non deterministic behaviour of object (re)configurations
during runtime in extbase will be a problem.
Compiled containers like symfony DI do not allow runtime
reconfigurations.

Also the concept of per plugin overwrites is broken anyway,
and should therefore be dropped:
The "objects" configured through plugin.tx_%name%.objects
are are never reset, that means:
Plugin A might overwrite an object and plugin B will implictly use
that overriden class, despite not having configured that at all.
(depending on the fact whether plugin A is rendered before or not)
