Since search engines are queried with a URL with a parameter for the search term, browsers could simply allow "power users" to enter a custom URL. Voilà — support for every imaginable search engine and they can still make their billion dollar deals for providing default search engines. That's how Firefox does it.
I think thats how everyone but Apple does it.
I just tested Brave. It's possible to set anything as the default search engine, but the UI hides it really well. They sure don't want you to find out. You have to add it as a site search first (which is a different section), then you can make that "default", which moves it up to the search engines and makes it the default search engine.
And sure enough, Safari on macOS seems to not allow it at all (needs extensions).
