Why Do Developers Continue to Sign with GNUPG

[fosres@posteo.de]

Hello Debian Security Team,

Since Debian is a major Linux distribution I want to ask why

software developers continue to digitally sign their code an

software packages with GNUPG when there are simpler alternatives

such as minisign (https://jedisct1.github.io/minisign/), signify, or age 
(https://github.com/FiloSottile/age).

PGP has been criticized for its being difficult to use by other

cryptographers:

I thank all responses in advance!
