I know you're an early adopter, but finding it surprising that the
current operating system is still being supported is a bit of a stretch, no?
Apparently I didn't express myself as well as I thought I had. I do not find it at all surprising that Apple is still supporting all of their current OS versions including Sierra, iOS 10, WatchOS 3, and TVOS ?? - in fact
I would be appalled if they didn't. However, given the current state of development of High Sierra,
et. al. and the current level of effort being devoted to the next round of upgrades I would be surprised if there were any new releases of the current versions other than a security patch/update if a vulnerability should appear. For anything else it would seem to make more engineering and economic sense to push improvements into the forthcoming upgrades rather than continuing two not quite parallel development forks running.
