I have never heard y’all used singular, growing up in the American South. Instead, as I understand it:

• Y’all: You all, referring to a group of people (Can potentially be a subset of a larger group, e.g. talking to one couple at the table among a group of friends). “When are y’all having the wedding again?”

• All y’all: shorthand for “all of y’all” Explicitly referring to “all of the members of the group in question”, requiring that at least one member of said group is being addressed by the speaker. The difference is there are no exceptions (apart from exaggeration) “Ain’t a single one of you innocent, all y’all had a hand in this” or “All y’all need to put on your seatbelts, I ain’t going to jail for any of y’all’s comfort”.

That was only ever a temporary fix anyway; Once the support substrate cracked, it was inevitable

Yeah, even with my relatively limited Esperanto familiarity (mi estas ankoraŭ komencanto, sed mi povas legi kaj skribi iomete), I was originally confused by it as well when I started using it a few months ago. Then when I saw the explanation on the faq, I just found myself wondering why the heck they used g instead of ĝ.

My local pizza places have actually started using DoorDash as their delivery drivers and it has me going and picking it up instead

The solution for me is that I run Nextcloud on a Kubernetes cluster and pin a container version. Then every few months I update that version in my deployment yaml to the latest one I want to run, and run kubectl apply -f nextcloud.yml and it just does its thing. Never given me any real trouble.
