Its the best way to find out if there's a mismatch between value and effort, and its the best way to learn and discuss the fundamental nature of complexity.
Similar to your argument, I can name countless of situations where developers absolutely adamantly insisted that something was very hard to do, only for another developer to say "no you can actually do that like this* and fix it in hours instead of weeks.
Yes, making a TUI from scratch is hard, no that should not affect Claude code because they aren't actually making the TUI library (I hope). It should be the case that most complexity is in the model, and the client is just using a text-based interface.
There seems to be a mismatch of what you're describing would be issues (for instance about the quality of the agent) and what people are describing as the actual issues (terminal commands don't work, or input is lost arbitrarily).
That's why verbalizing is important, because you are thinking about other complexities than the people you reply to.
