Python actively encourages you to write the python shebang explicitly
either #!/usr/bin/env python2 or #!/usr/bin/env python3 for scripts
that are not compatible with one of them. It is no longer practical to
make any assumptions about the python version in the (unversioned)
python binary, therefore your argument about java doesn't hold. Since
the developers themselves support this conclusion [0], there is no
reason to still have the symlink and hence we should actually abolish
it completely, which I expect to happen in the long run.
