I mean a lot of it is just that many features that would have been nice to use decades ago have only just been implemented. For example, now we have some great modal options built into the browser in the form of the dialog element and popover attribute.

But for years, those didn't exist, and people got used to that. The former was added to certain browsers in 2022, and the latter was added in 2023-2025. If you've building modals with divs and JavaScript for years, it can take a bit to realise you don't need to do that anymore.

Eventually I suspect we'll be in a place where self-made solutions for common UI issues aren't needed anymore, but that's still sadly a way off, especially given how slow browsers have been to add fully customisable select elements and other form fields.
