I'm not clear how that's a good analogy. Is it?

Perhaps my response here is overly detailed, but it appears that you're
making a quite detailed technical point. So:
1. Actually, at least for Neutron ML2 drivers, Neutron does not provide
namespace arbitration. There is a setup.cfg entry point space with the
name 'neutron.ml2.mechanism_drivers', and each 3rd party driver adds its
name to that space. But there is no explicit protocol here (i.e. where
networking-calico would say 'Can I use the name calico?' and Neutron
might answer 'Yes'). De facto we just hope that there will never be
clashing names in a given deployment.
2. Note that the names used here are project or code names. For example
'calico', not 'OpenStack L3-only Networking'.

Yes, but that doesn't necessarily mean 'OpenStack Networking' rather
than 'Neutron', I think.
