[T5] multiple configurations for a service?
In T5 ioc, what is the recommended way for having multiple configuration
points for a service? Do you do something like set up a service that is
internal specifically for accepting contributions and then inject that
into the real service being configured?

This is an area where there was simplification from HiveMind to T5 IoC.
Basically, in the relatively rare case that a single service needs
multiple configurations, there really is not an alternative to
creating different services, each one managing a specific set of data,
with a "master" service that depends on the data services to access
the configuration data.
This doesn't work too poorly in practice; for instance, this is how
Infrastructure and InfrastructureOverrides works. There's often some
value add to separating out the concerns (related to the contributed
data), such as simplifying the testing of the master service, since it
does less.
