You say that it makes perfect sense, but you don't explain why.

Yes, that would be the only sane way to do it, but I really don't see a 
benefit large enough to compensate having a different treatment for 
classes depending on some arbitrary line like when they were added. The 
only real benefit of namespaces is to avoid name collisions, but most 
new projects use namespaces and we can easily avoid name collisions in 
the PHP core.

Plus, remember ext/intl is maintained in PECL too, where it supports 
PHP 5.2.

Anyway, this is getting a bit off-topic.
