We're quite a ways back, but I do the development and I run on 1.28.1
(both NiFi and NiFi Registry). We have plans to move to 2.x someday.
It's hard to get customers to move forward.

We don't use a separate Git repository; only the simple solution the
NiFi Registry offers.
Maybe someday we'll go further, but, in the meantime, It's super useful
to us so we hope
never to see it disappear.
