Hi,

thanks for the reply. I see your point with the legacy distutils.

Given the constraints, yes, it would be good to have that warning in the docs. Even better would be a runtime hint like

Notice: gztar target will preserve symbolic links.

or

Notice: zip target will dereference symbolic links.

That would be very welcome. I am afraid I will not be able to contribute code anytime soon, but it would be great if the regular developers could keep an eye on this inconsistency.
