I still have older versions in my environment. As long as the older clients are still able to send reports to servers running on the newer versions/OS's I don’t see any problems dropping support for the older OS versions. There's no breaking change here, we're just not releasing new software versions for older OS's. Along the same line, I don't think it would be a problem to use 4.4 as long as the older clients are able to send reports to the server on newer versions.

I don't object to a significant change in backwards compatibility in
concept.

I think that any such significant change in backwards compatibility
should likely be done at a major version number. So how about 5.x
instead of 4.4.x

Just my opinion.
