Yes, this is what should be done.

When the C++ ABI changes in an incompatible way (like it did a year ago),
there will anyway be a complete ABI transition in Debian - any
potential issue would not be specific to wxWidgets.

Matthias Klose confirmed that ABI version 10 is supposed to be backwards 
compatible with ABI version 9.

I'm closing the binNMU request and move the other bug
to src:wxwidgets3.0
