"Darts" was just a play on "bullseye". It is not hard to imagine
a repository which has the same suite and component(s) but is not
Debian itself. As a pseudo-random [= its in an other topic here] real
example you can take Wine (https://dl.winehq.org/wine-builds/debian/).
So to what is "deb apt:// bullseye main" referring? Debian or Wine?

And to pre-empt the most common response: As an apt dev I can assure you
that we won't accept a solution involving "I am on Debian, so it means
Debian" as that is impossible to correctly guess programmatically (for
example on derivatives using a small overlay repo).

Because this thread started with the idea to switch the default of d-i
and co to another URI. If you target only apt then you still need
a solution for d-i and a way to convert whatever d-i had into what apt
gets in the end (of the installation).

The configuration option which only works with apt tools already
exists in the form of the mirror method…

And I have no idea if you know what you are talking about.

auto-apt-proxy already uses an interface apt provides to configure the
proxy at runtime. It isn't in the business of modifying sources.list nor
has it any interest in that. So you using it as an example for a plugin
who could use your proposed scheme to modify the sources at runtime
makes no sense.
