I think a compromise - that is similar to signing tags but would still work with the github process, and leaves a trail after merge - would be: if you submit a stack of commits, only sign the most recent one. As each commit contains the cryptographic hash of the previous commit, which in turns contains the hash of that before it up to the root commit, signing every commit if you have multiple in a row is redundant. I'll update the document and put it in the repository. Wladimir
