I have no idear how "accessibility" is defined. I'd say getty is quite accessible, but well, I don't know, I never relied on it. But yet, that is no excuse to start a hole desktop. Just like a program can use gtk (theoretically) without a gnome desktop it should be able to do the same with for a braille display.

I think I can safely say that if X breaks Y, and I need Y than X sucks. Especially if it worked before X came. X made things worse.

/edit: I think that's why Poettering is hated so much. There was community on the Nixes, with their own ecosystem and their own way to do stuff. It's wasn't always beautiful or nice, but their had their way to solve stuff so it would a kind of blend in with the rest. And then Poettering wants to turn it into MacOS X or Windows and adds stuff new users probably appreciate, but the old users never misses. There is a cultural shock. And then it breaks backwards compatibility. It shouldn't suprise anybody that this product should rather be superb and not just medicore to accepted.
