R17.1 - macOS Requirements

Hi.
I recently updated my version to R17.1 and it works excellently, as I suspected it would
One thing I did note is that the minimum system requirement for a Mac is "macOS 10.15 Catalina." Interestingly I am running it fine under "macOS 10.14.6 Mojave," and, if there is a version checker running within the installer, it clearly doesn't seem to mind.
Can anyone enlighten me as to how long this nice state of affairs will last? My main computer (a MacPro 5,1) is no longer supported by Apple and 10.14.6 is its terminal operating system (without resorting to hacks). Given the message, I suspect this 17 series will be the last but it'd be nice to know, officially-like
Thanks for all the excellent work!
