-------------------------------------------------------------------
Thanks for your input on this Thomas!
In the context of my usage, all the changes were already made and I just need
to digitally sign it, thus, the COSWriter problem doesn't affect me. That being
said, if this is not to be supported, the final PDF shouldn't have any mention
of a digital signature and it should be explicitly stated in the API
documentation (specially because the saveIncremental doesn't states what it
actually does different).
All in all, it would be great to have it supported nonetheless :)

> Assignee: Thomas Chojecki
> Priority: Blocker
