Well LaTeX itself redefines the primitive \input, so LaTeX itself is
inexcusable ;-). 

Beside this amslatex doesn't "undefine" \over. The old meaning is
stored in \@@over and you can easily restore it if you want. 
And even if it would undefine it, you could easily save the meaning
yourself before loading the package. So what?
