I do take your point, but I was intentionally testing something as baseline as possible across all the remixes. So, no VBox guest additions, no extra drivers, etc.
TBH I am very surprised that they shipped such an old version. I mean, LXQt came out *last year*.

They have had abundant time.
OTOH, the vertical-taskbar functionality is broken in LXQt 1.0, and LXQt 1.1 came out just a couple of weeks before 22.04.
I could understand reluctance to ship a one-point-zero version of anything.
It is worth pointing out that only the vanilla GNOME Ubuntu is technically an LTS: if you want Canonical's paid support, that is what you must run. Remixes do not qualify, official or not.
As such, I think it would be perfectly fine to ship LXQt 1.0 in 22.04.1 and LXQt 1.1 in 22.04.2, which is due next February.
