You're trying to tell us that software from 2019 isn't new? The majority of the software that I use on a daily basis is minimum a decade old, and I don't think I'm alone.
I've reviewed both the design and implementation for age in the past and only found nitpicky things to improve (mostly related to HKDF).
I can take a fresh look and make a pretty PDF on paragonie.com if you care so much.
