I don't have a gnome session in my login manager because I don't need i18n for the words "login" and "password". (although that would be totally possible without a whole gnome session). I don't have a braille line so i can't say anything about accessibility, but that should be (in a ideal unix world) a single printf to /dev/braille. Also the feedback is audible and visual, this seems to be no issue to me.
Edit: Plus saying X breaks Y so X is not needed is not a good argument. Because you have not addressed if X is needed or not, only said that Y breaks.
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.
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.
