It seems weird to me to gauge someone’s understanding of “brand new” for cryptography software by measuring against primitives and constructions. To me at least, those are not the same thing. Even if a piece of software contains cryptography I will still also evaluate its age as a piece of software simply as a proxy for maturity and stability of the feature set.
No it was a comment trying to indicate that I found your question odd, and ask why you think your question is useful? Do you believe there is a single notion of brand new that can be applied across all categories? Is the age for brand new milk the same as for software or for scientific results or items of clothing? Or do you believe that for the categories of software and cryptographic theory the notion of brand new is equivalent?
Frankly in my reading of your question you come across as very arrogant, where you use the guise of a “serious question” to show off your knowledge cryptography.
I also agree with adament. It may not be responsive to your question but your question doesn't read in good faith and many of your other comments in this thread read as pitiless war against an opponent you've decided is your enemy.
There have been many articles written that push back against the narrative a small cohort of security people push that GnuPG and OpenPGP by extension should be avoided at all costs. Personally, I find it has stood the test of time admirably and that its "multi-tool" functionality unlocks features I use almost every day like a web of trust in Keybase and using it as an ssh agent. I actually don't want another tiny tool in age. With Sequoia the future of PGP looks bright.
