When will we ever get the option for a custom search engine? (Safari)

So as you may know, i am a guy mostly focused on privacy. Basically, insead of google i use SearXNG. (Privacy focused search engine) However, when i went to change the default search engine in safari, there was no option to add a custom search engine.

This really pissed me off. So how come Apple allows changing default browsers in the EU, but not search engines?
