I think you can even add the symbols (and remove the unversioned ones)
without other than ld.so yelling a bit at you occasionally.

if your <thing> needs a versioned symbol, then the version must match.
If your thing doesn't need a versioned symbol, then any symbol,
versioned or not, can be used.

(I'm only talking about glibc's ld.so)
