Well to be fair, the core function of ACF, you can do without the plugin. Like internally, ACF is just a post meta. You could implement it the same way or as a custom taxonomy. WordPress gives you everything you need for that for you to just build it.Matt should have invested some of the ungodly amount of dev hours that have gone into Gutenberg into making Wordpress a better CMS and made a native version of ACF.
It just happens to be that ACF has a nice UI attached to it where you can use this without modifying any code. And since I get it that many users probably don't need custom fields, I feel like it's ok that it is a plugin.
But they really really REALLY should implement a 2FA login system. Which is missing. In 2024. THAT is a shame.
