I'd like to avoid having to do a "Switch to desktop version" button at almost all costs, because
a) we can't easily do it. The SMF mod we use to give responsiveness to the site relies on CSS to decide which layout to use based on the width of the display, not some kind of mobile-desktop-browser-detection-stuff dark magic that was usual before this could be solved with CSS. So we'd have to find a way around all this to make such button work. And, more importantly:
b) it'd be a step in the completely wrong direction. The world of making webpages is going more and more mobile first and mind the desktop version only after the mobile one is done. So that's what I am intending to do as well, because I find it more sensible, too.
So all in all I happily take the blame if someone says the mobile version is bad / lacks stuff / etc. and try my best to resolve it, but the solution for me is improving the mobile version, not going back to the hell that is pinch-zoom-in-out-scroll-scroll-scroll-browsing the desktop version on a tiny screen.
