Re: author specification
Message ID:
But I'm understanding from this conversation is that people have different
ideas of what the auth field means.

1. It shows who is responsible for this code. It is independent of which
home the author chooses, where home is GitHub, gitlab, cpan, zef,p6c etc.
2. It shows who is responsible for this code, and its main home. Auth does
not change when stored on other homes.
3. It shows who's responsible for this code in this home. It changes
depending on which home it is being uploaded to.

So it helps to consider some cases and how we handle it.
1. Long time Perl contributor has a CPAN authority, and decides to migrate
all existing projects to github as a main home.
2. Long time perl contributor has a CPAN authority, no Git account (local
development). She decides to distribute new Raku projects in zef primarily,
mirrored in CPAN because she loves metacpan's API and interface.
3. New contributor has modules in GitHub account, is agnostic as to
ecosystems. Wants every ecosystem to reflect latest pushes to main branch
in their git account.

How should the auth field work for these cases?

More cases welcome... (Welcome to the bikeshead? 🚲🏘️🔵💚💜😢)
