just imagine flying at, say 1,1 Vso and then try to go-around – on most low-powered aircraft you will probably mush down to the runway
No. Most aircraft most of the time can perform a go around at any time on the approach up until touch down, even in the flare (when you might be at or below the S&L stalling speed).
Exceptions occur, like very hot or high conditions. They're - umm - exceptional.
