Can relate, after 7+ years I am again using WordPress and PHP again. I am impressed by PHP 7.
You're not alone mind you, most of the new platforms are not very popular just because of how embedded WordPress is in its ecosystem. It just surprises me that both WordPress never moved on and that the PHP developer community never chose something different when it was clear WordPress had no intention of moving to more modern practices.
Imho the best CMS for PHP.
Have you ever tried it?
It was the only CMS I could find that had the level of simplicity I needed.
What are the amazing option do you suggests with batteries include in the language would be ideal.
