For ob-python, there is little difference. I am thinking in a more
general context of all the babel backends that support sessions.

python.el is convenient as it allows setting the session buffer name in
advance via buffer-local variable. Then, all the normal python-mode
commands, including `run-python' or `python-shell-send-region' will work
as expected. However, other babel backends like ob-R do not have such a
luxury (see the dance with renaming R process buffer in
`org-babel-R-initiate-session').

That's why I thought about remapping `run-python' and all the equivalent
commands for other backends.

However, as in the above example, `run-python' is not the only mean to
initiate session in various major modes - sending a line or region at
point is another common command; and they might be others. Not to
mention that re-binding is not panacea - people may still run the
original commands via M-x.

So, re-binding is probably not the best idea.
In other words, `org-babel-python-run-python' is not necessary.
