For me the biggest advantage of old UI on Reddit was with what RES could provide in terms of keyboard shortcuts etc. Since this doesn't seem to have that, for me I don't see a whole lot of value.

Discussion about the aussie.zone instance itself
I like it,but am scared to use it if it might be taken away
It's just a UI, all the content itself is in the same backend. It's very light weight to host, so I'd only shut it down if it has issues.. eg security or interop with future Lemmy versions.
Speaking of security,.an abandoned app is a prime candidate for capturing user/password....
Thing is... I'm not sure if its abandonded, or there have been no breaking changes in recent versions of lemmy so no dev work has been required. Last release was in July, and the dev himself has been active on Github recently.
It's nice to have access to a compact layout. The in-built Lemmy compact themes are ineffective, as far as I can tell.
Old is always nice, but indeed the dev doesn't seem active anymore
