Versión obsoleta de gpg en Big Sur

Parece que el actual gpg instalado en Big Sur es un poco anticuado comparado con el embotellado de homebrew .

gpg --version

Similar si pruebo con gpg2

Si no me equivoco con la versión actual parece que no hay soporte para algos de curva elíptica, por ejemplo. ed25519 .

Brew dice que la última versión de gpg es 2.3.4

brew info gpg
gnupg: stable 2.3.4 (bottled)
GNU Pretty Good Privacy (PGP) package
https://gnupg.org/
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/gnupg.rb
License: GPL-3.0-or-later
==> Dependencies
Build: pkg-config 
Required: gettext , gnutls , libassuan , libgcrypt , libgpg-error , libksba , libusb , npth , pinentry 

Las ubicaciones de las versiones de gpg instaladas son las siguientes:

which gpg
/usr/local/bin/gpg

which gpg2
/usr/local/MacGPG2/bin/gpg2

Mi pregunta es si desinstalo gpg y gpg2 y luego instalar usando brew ¿tendré algún problema?

O dicho de otro modo, ¿cuál es el método adecuado para actualizar el gpg versión 2.0.30 a 2.3.4 .
