Parsoid/PHP is currently used as a faux extension. We adopted this strategy so as to speed up Parsoid/PHP deployment while waiting on PHP 7.x adoption, and addressing technical debt. Now that Parsoid/PHP is in production, and the production clusters use PHP 7.x, we can address the technical debt pieces in Parsoid and stop using Parsoid/PHP as an extension.
Subtasks will address specific aspects of this work.
