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.
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.
