Yes, any GUI that doesn't provide any kind of RPC or composable API layer is almost a lost cause to me. I'd personally refuse to use it. With a caveat, though: on MacOS, which I absolutely abhorred in the beginning, having now been required to use for work (instead of Linux), I found the beauty of OSA (Open Scripting Architecture). Holy mother of Turing, I wish there was anything similar on Linux. I had no idea how amazing this thing was. I can fearlessly dig things out of even complex UIs for automation in ways that I can't ever dream to be able to do on Wayland. That still not an excuse - any serious UI should provide a functioning API.
