In that case, what I would recommend is: Use your handmade solution,
but call it SimpleNamespace, and make it entirely compatible with the
Python 3.3 one. Then, when you do get a chance to upgrade, all you
need to do is change your import statement, and you're using the
standard library one. Plus, it's going to be easy for anyone else to
read - they'll already know what SimpleNamespace does and what to
expect of it, so they don't have to dig around to see what your class
is doing.
