It occurred to me that, because I have a number of projects that implement their own command loader, that exposing an “Aggregate Command Loader” that could accept multiple command loaders at runtime, perhaps by way of a delegator might be a useful addition - For example, provide a _default_ aggregate command loader via configuration that consumes the current container command loader and expose a public method such as `addCommandLoader(SymfonyLoader $loader)`. Then is becomes easier to bring multiple sources of commands together in a single cli tool.

Alternatively, the aggregate could require an iterable to its constructor such as `config.laminas-cli.command-loaders`.

`get` and `has` inside the aggregate could just iterate over the configured loaders in order of registration… or perhaps in reverse order, meaning that loaders registered later on could override commands configured earlier - this would work nicely with the shipped ContainerLoader that attempts to new configured commands when not present in the container.

This would require shipping a ConfigProvider / Module, but the cli tool could conditionally create a `ContainerCommandLoader` when there is no `AggregateCommandLoader` available in the container.

It might also be desirable to alias this `AggregateCommandLoader` to the Symfony command loader interface making it the intended single source for commands…
