As said, there are currently three engines + two forks of these (Gonanna and Qt), except some basic render engines from text only browsers (Links, Lynx and some others), but over hundred different browsers which use these engines, + almost 70 abandoned ones, because outdated engines and others which also tried to develope an own engine. This is what I mean with saturated. It's nice to try to release a browser with a new independent engine, but if there are not enough users which also use it, it's a death born child. For some products the market is limited. Make it eg. sense to release a new OS? There also existing only 4, Unix, Unixbased like Windows or Mac and Linux with tons of distros. It's not only the browser engine, in over 20 years there are also growed complete infrastructure arround these engines, dedicated plug ins, extensions, etc, which don't exist for a new indie engine, precisely because other browsers, which also tried to release a new engine, before Ladybird, are currently all death. Sad, but you need also a minimum of infrastructure for an browser and which offer also somewhat more as only a new engine. It need security and privacy measures, inbuild or with extensions/plug-ins which need an extra developement and other things more.
