Entity identifiers aren't RDAP 'entry points', though, in that there
are no guarantees that you can take an identifier from some other
context and construct a usable query like
'https://rdap.example.net/entity/$identifier' (putting RFC 8521 object
tags to one side), so it's not clear that it actually imposes this
requirement.  For example, it's open to an implementor to prefix their
existing identifiers with strings describing the underlying object
types, in order to construct unique entity handles.
