I’d expect them to update at some point, but I don’t think there’s a current value that’s taken as a “N releases back” that as a community we try and support. I think that’s something the ecosystem team is talking about proposing, but nothing is out there yet. When that’s pinned down, I’d expect that perhaps one of the release tasks would be to update the various workflow defaults.
In the meantime, this is entirely configurable per repo - the swiftlang worklows are very nicely set up that way, so if any repo wants to use it, they can, but since it’s the current default, I at least wanted to call it out and provide a path to work around the transition.
