Handling of unversioned upstream sources

[Jochen Schmitt]

Hello,

unfortunately, I have found some review request, where the upstream only 
offers
unversion sources.

The issue of this sources is, that you will not be able to access to the 
upstream code in the
future, if the upstream has changed the content of this unversioned.

So I want to ask, if there any guidelines about this topic?

Best Regards:
