Have you considered reaching out to folks on the IRC for feedback? These issues look to have been open for a while, so the automated build farm has likely forgotten them; I'd love to have a mainlined approach for Podman
I feel kind of bad about this but I refuse to join Guix IRC. I use mailing list out of frustration but these communication channels are the proof that Guix is not only a nice, useful and open project but it has born a project for fossbro babyboomers. It is a golden walled garden for themselves , I don't feel ok in that space.
EDIT: I've answered a little emotionally. Let me clarify, I believe most Guix maintainers act of of good will and they want to find some communication platform which is inclusive for everyone (since it is clear also to rocks that IRC is good only for someone born before 1990, so it is good for people aged >= 35) . Some of the maintainers, and some most noisy members of the community make it so bad for everyone else but themselves that, having so much explicit and soft power, the discussion about moving away from communication protocols older than CDs was closed stating "everything is perfect as it is, we reach exactly the right set of people, we do not care of increasing the userbase or making the community more inclusive".
I’m not too bothered by the IRC, it is a bit annoying not being able to get messages/responses while away (unless you rig up something to stay connected), I haven’t tried the mailing lists yet (other than the ones used as part of the Guix patching process (which Guix does provide a nice UI for with issues.guix.gnu.org), but it was a real pain connecting git:send-email as a first time user for the send-email part. There is supposedly some new tool called Mumi, but I haven’t tried it yet.).
I don’t see what you mean about the IRC being a walled garden? It did take a bit more work to connect than registering for Reddit, but I’d say it is comparable to the effort of joining Lemmy (but without the nice persistence of Lemmy). Another reason they might have for not wanting to add more communication channels is maintainer fatigue, every communication channel they officially add has to be watched by someone; and if all their maintainers are comfortable with something else, they will have to take time out of their day (with them already likely being volunteers) to monitor the new channel.
