If this ever happens, you should be able to find the information by
searching NEWS for "C-o".

So I think you are inventing a problem that doesn't exist.

I hope you now realize that changes in bindings like that are not
catastrophes, and you can easily resurrect whatever binding you fancy,
using NEWS and other means to find out the names of the commands you
never bothered to discover.

(Btw, does this mean you never use "C-h k" to read about the commands
you invoke?  Never, ever?  Because if you do, the name of the command
is spelled out there, on the very first lines of the *Help* display.)
