I'm happy to see this, however I'd be far more excited if I thought there was a chance of it landing in the upcoming Ubuntu 20.04 release - else I'll likely be waiting impatiently until 22.04 for server-side support.
Likewise, I would be glad to see it in 20.04. According to this page, https://wiki.ubuntu.com/FocalFossa/ReleaseSchedule, feature freeze for 20.04 is on the 27th of February so I don't see any reason why Openssh 8.2 can't make it into the LTS. Unless there are other considerations I'm not aware of.
It'll probably make its way into the backports repo. While that does add some complexity to managing your system, it may be worth it in this instance. YMMV.
