Why? PGP needs to be deprecated in favor of things like AGE and Magic Wormhole.
Everything else is either not used in practice or needs to be shifted to a dedicated protocol.
There isn't even an explanation on that page of why it was written, why it should (or could) replace OpenPGP, how to replace it ( a handy comparison table), and which use cases the tool is good for. It'd be really great if instead of pushing for change, you'd actually provide some context and explanation.
Everybody can scream for change, few can understand (much less explain) the why and how. Maybe try and join the latter.
