So far there has been no further reaction on the ticket, so I hope there
is not much more breakage. :)
Some transitions take a bit of time.

This means giving up on system packaging and I do not agree with the
mentality of hiding away all legacy in a container.
That's neither beneficial for us nor for the upstream projects or for
the diversity (in regards to how to use and run a piece of software) of
the ecosystem in general.
This also means that running and installing this software in an Arch
Linux based container would be not supported and/or flaky as well, which
I consider a detriment to the distribution :-/
To spin this wheel a bit further: What is the point of having a php
package, if it could also be provided by an upstream container?

That's what we usually do and that is also what keeps momentum in
certain upstream projects.
FWIW, that's what we do for the entire python ecosystem for better or
worse and more specifically for e.g. python-django, which has a few
dependents that can not easily be upgraded from one minor version to the
This sometimes means getting involved with upstreams, providing patches,
using patches, etc. which is part of the packager role that we are in.
However, the problem we are currently facing is that of upstream
frameworks and languages being unable to provide sufficient
For this we need to make a greater effort to have testers and more
clearly defined (automated) test scenarios. If we can not make this
effort to some (even small) extent, I'm wondering why we are packaging
languages at all anymore.

Wouldn't this mean that those php versions are mutually exclusive?
I would be more in favor of moving towards a unified php version again,
else we might end up with a lua or java situation eventually.

I don't think the option to "move faster" is a good one if there is
nothing that is outright compatible anymore ;-)
What would be the target of an up-to-date php, that has no packages
With a two version system (that is mutually exclusive?) we would have
the same issues with incompatible projects as soon as we move from one
version to the other, just at a different point in time.
We have version constraints to guard against these major/minor version
upgrade scenarios and to be able to have an overview as to what is not
yet compatible and then act based on that information in a testing
I do not believe abolishing that just so that we can upgrade and break
everything without even knowing about it makes a lot of sense, but maybe
I did not understand your intentions correctly.
