For example, I see you used mac80211_hwsim and was able to use two
wlan interfaces to talk to each other. This seems great for testing
purposes but it remains unclear to me the advantage of testing with
separate namespaces vs creating two wlan interfaces on one namespace
with mac80211_hwsim.

You cannot ping within one namespace and have the packets actually flow
over the virtual 'air'.

I see, thanks! How does using a separate namespace fix this limitation?

Well that's the magic ;) Think of it as having one copy of the
networking stack per netns.
