As I’ve tried to implement my minimal ssh client (just to connect, execute some command and get the result) I’ve had exactly opposite impression of the “just a stream of bytes” that you mention -- exactly the lack the abstraction. Can you point to any source that does ssh without having to care about a lot of weird terminal and console ancient stuff? I’d be really glad to see it! To me it looked as “everything and the kitchen sink” (that is, exactly the kind of things mentioned in the OP or the comments, like terminal signals and whatnot) has to be there. SSL is straightforward compared that, at least, once the keys are set. But ssh... as seen in the OP even the console or the terminal or however that part it called has to be very special, and they are obviously proud they implemented that too. In 2018. Probably decades after the last single hardware terminal was sold. |

I think there is probably a lot of room for improvement in the terminal world, and I agree that a lot of the really old stuff makes things a bit counter-intuitive, but for whatever reason, it seems that people who make really good software also tend to be the people who are pretty fanatical about backwards compatibility. Consider vim, for instance.
In the end, I think the basic model of interoperable, small programs that manipulate streams of text is really good - so people will put up with any number of weird rituals to live in that model. It's also very humble, and very unexciting, so it's the kind of thing that's hard to get people hyped about. So it probably filters by the people that like old things.
