At some point you have to have some accountability to your users if you want to make software that has a good user experience.
And Linux on the desktop doesn't. There aren't incentives in place to deliver the best user experience. The Debian maintainer can disable your password manager because he's decided that password managers with hardware key support are "crappy," and there's no repercussions. (Sorry, I'm still not over that.)
This is the status quo with a lot or most volunteer-developed software. Stuff gets done because it's easy, or because it's fun, or because it aligns with the developer's conception of what the software should be. This is true for my projects as well of course.
LadyBird is going to fall into the same trap—the websites that are easy or fun to get working are going to work, and the websites that are annoying and painful to get working aren't going to work.
This might be the first time I've conceptualized a problem with volunteer development. (I guess the second, after the time one [1].)

Some of this is mitigated by the developer being a user. But not all of it. Modern Minimalist is going to have to include some incentive to listen to your users.
