As I noted, the dynamics have changed significantly. I'd say that core
committer team as a whole is now much less conservative than before,
although they're still just as dedicated to internal backwards
compatibility.

As an example, it's looking like PDO is almost a certainty for 3.6. It
will mean some backwards compatibility issues though, so a while ago,
this wouldn't have even been considered.

(Note: I'm not a core committer, mainly due to never having the time to
commit to it, but I am heavily involved in WP development. I'm also
single-handedly responsible for ~10% of the codebase via SimplePie.)

Namespaces don't matter to WordPress really, since it'd only be new code
using them anyway. Changing existing class names would be a huge
internal backwards compatibility break which I doubt will ever happen.

Closures, as I mentioned, don't work well with our action/filter system.
Basically, in order to be able to unregister a callback, you need to
pass in the exact callback that you registered it with; with closures,
this isn't possible unless they're assigned to a variable, which defeats
the purpose.

Here's hoping. :)
