I can't comment about other people but to me the reply felt like denying my personal experience of those three frustrations (because yes I am frustrated with W11) of which two seemed ignored and one presented with a solution which I already tried to no avail. If you had acknowledged the other two in the initial answer (like in a "at least for position..."), I'm very sure I wouldn't have reacted. Small things can make or break...
Now the aside being put aside, I have no idea why you have a setting and I don't, as I'm on the latest updates. Could be that Microsoft is doing some A/B testing? And is the left positioned taskbar working fine for you? I still won't switch until at least drag&drop comes back but it would be a glimmer of hope.
