Description

  • Allow an application service to register usernames starting with underscores if its configuration file allows it.
  • Support non-exclusive namespaces.

The latter means we shouldn't respond with Only 1 match allowed-like errors if a user ID provided during registration from an appservice matches more than one namespace and none of these namespaces is defined as exclusive. This requires checking whether a namespace is exclusive during registration.

Contributor guide

Research direction
Inspect the registration handler in Dendrite and check if application service namespaces are properly checked for exclusive flag during registration.
