This allows nonexistent translated pages to fall back to the
corresponding page in a suitable language.

Use paction 'metadata' instead of 'parse' by default, to avoid
accidentally using VirtualRESTServiceClient when testing cases
that don't require it.

For readability. The current implementation is a sequence of
7 (!) array_…() function calls. It is also not free from bugs.
If one of the two inputs (ExtensionRegistry and Config) specifies
namespaces by e.g. canonical name, but the other by number,
the two are not properly merged. It should be possible to use
configuration to disable a namespace that would otherwise be
enabled. This currently works only if both use the same array
keys.
