Thanks for bringing this topic to internals@!

In my opinion, this extension should start as PECL extension.  This
would allow it to be developed independently of the PHP release cycle,
and the API could be adapted if necessary.  After the extension has been
stabilized, and if the extension turns out to be generally useful, it
still could be bundled.

Thanks,
Christoph
