Flow has a new namespace: Topic. It has an even

Talk pages till now have had odd numbers, and some scripts relied on that.
And that is still the case. For example,
https://www.mediawiki.org/wiki/Talk:Search is a Flow-enabled talk page, and
its wgNamespaceNumber is 1.
So it's still a reasonable assumption that the talk page for a page is in
the odd namespace N+1.
Now the topics that appear on every Flow board page are in this special
Topic: namespace and that is not odd but 2600. But this is not the talk
namespace for the regular pages in namespace 2599, it's a specialized
namespace like Graph or Worfklow. A Flow topic like
https://www.mediawiki.org/wiki/Topic:Savgw0ltqlin3m69 is not the talk page
of anything.
I don't think there's a technical difficulty in making NS_TOPIC odd, but
it's implying things that aren't so and I'm not sure what the win is.
(it might be related because once we have more than a single namespace
associated to
a given namespace, the parity of its ID might not be that much
relevant anymore...)
