Is it easy / recommended to bundle `python-future`?

[cdeil]

There's a lot of projects that bundle six to avoid an extra dependency (see e.g. scipy/lib/six.py or astropy/extern/bundled/six.py.

Currently the python-future docs don't mention the option of bundling it in other projects I think:
http://python-future.org/search.html?q=bundle&check_keywords=yes&area=default

Could you (maybe as a FAQ entry) comment if bundling python-future is recommended or not, and how one should do it, i.e. which files / folders should be copied over?
