Should we want that?
I think I really don't like even the concept of Editions. The
reason for that it stems from an incorrect assumption about how
software debt works.
Currently the maintenance cost of a library is paid by the
library maintainers (if any). I'd argue people come to languages
because of arguably alive libraries, and dead libraries less so.
That an abandoned package build will not help much if it's not
maintained and say, does not work on Windows arm in 2030. And the
cost of keeping up with the times is often larger than dealing
with the language and Phobos changes.
In some economic terms, the dead package did not enough interest
to pay for its survival.
The burden on the core team would likely be unfair and increasing
over time, since now the compiler developers must pay the debt of
abandoned code that should have died, code that they are no owner
of.
If you want people to stop stumbling upon unmaintained code, then
either hide more of it (DUB registry could do that), make the DUB
ratings more reliable and transitive maybe. We have an increasing
number of high quality library but the dead libraries that
somehow were registered to DUB accumulate linearly with the
passing of time (in the same sense that more men have died than
the number of men that live today).
When alias this breaks the important thing is in my
not-so-informed opinion "why DlangUI has few maintenance energy"
not "how can we make it still build".
