> When you modify the set of {{LookupLocator}} in use by {{LookupLocatorDiscovery}} the
lookup locators considered equal as in {{LookupLocator.equals}} are ignored, although they
can carry different constraints with them such as with {{ConstrainableLookupLocator}}. This
means that when unicast discovery fails for a lookup locator due to 'wrong' constraints, and
you pass in a new lookup locator with different constraints (that might make discovery possible)
the retries will continue with the earlier lookup locator passed in.
> The problem here is that lookup locator equality is or not properly specified, or the
{{LookupLocatorDiscovery}} utility must assume lookup locators passed have non-trivial characteristics
that won't surface by calling equals on them.
> This issue is closely related to how we should deal with changing security requirements
over time.
