I've been building https://github.com/Qbix since 2008 and let me tell ya, I took a lot of great ideas from Drupal, Kohana, Symfony, etc. But never Wordpress. It's just ... a mess. Wordpress just won by being first, basically. Kind of like Bitcoin.
PS: Years ago, I hired a guy in Pakistan to work with me on some Wordpress sites, for clients. I thought that the Divi theme and basic Wordpress would be secure. Every one of those sites got pwned, badly. Sure, maybe it was the plugins. But why take the chance? In 2026 it's way past time to not have to worry about basic security.
