No not really, just python, zope and z3c libraries,
on windows some win32 or ctypes.

I think using packages with deprecated code is just a workarround
if someone needs to use new features which is built in a 
newer version of a package and can't use all the newer
versions of the packages this package depends on. (BBB)

The better way is to use the old package or the new set of packages.
I agree that this is not always possible. But we should not
excuse us and tink that this is correct. It still has a hugh
potential of problems because the set of versions is based
on BBB and this part is not well tested or test are removed.

Most the time if you will run into unexpected problems,
some untested old BB code is involved. Take a look at the
old registry code in our zope packages as a sample.
