Maybe, but that's the magic of LLMs - they can now one-shot or few-shot (N<10) you something good enough for a specific user. Like, not supporting multi-desktops is fine if one doesn't use them (and if that changes, few more prompts about this particular issue - now the user actually knows specifically what they need - should close the gap).
