Yeah, I agree. While Wordpress itself is impressively functional software it would surprise many people just how shaky the foundations its built on are. The PHP ecosystem has never had a strong reputation for quality engineering, and Wordpress originates from a time when quality in that ecosystem was at its lowest. Ironically Wordpress's failure to modernise is actually key to its success - not making changes has allowed its plugin system to be very stable and maintain a lot of momentum. By comparison Drupal, which has done its level best to drastically improve its code base over time, picking up best practices like composer and using Symphony, has completely fallen to the wayside because its module ecosystem couldn't keep up.
