Hi Uwe I agree with most of what you say. The issue that occurs fairly frequently on this forum is people who are respected for their broad knowledge on Indesign saying flat out that it is not possible to run CS6 on current MacOS or that it doesn't work with retina screens. I'm guessing that those same people have never even tried running CS6 on modern systems. I don't expect them to as they, like a lot of others have fallen into the CC system and don't have any need to use CS6 any more. But, if they have no knowledge of the realities of using it then they should refrain from making absolute statements on a subject they don't understand. As you say, any version of Indesign can be made unstable by OS updates or people using third party extensions to other software, so there is no greater risk to use CS6 than there is to use CC2017. You say yourself that problems 'could' occur using CS6, not 'will' occur. And while it is obvious that CS6 will not be getting bug fixes from Adobe, from my long history of working with Adobe products - and Indesign since version 1.5 in particular - I can categorically tell you that a lot of bugs are never fixed. I can also say that CS6 will never have any new bugs introduced but CC2017 will definitely gain new bugs with every update. CC2015 ended it's life with a fair few irritating bugs still unfixed. I suggest that they will also never be fixed because Adobe have now moved on to CC2017. On a personal note, I run Indesign CS6 (the full versions, not the CC version) every day and all functions work as well as they ever did. It is extremely fast on a brand new iMac using Sierra. I also use CC2015 every day and experience some crashes, palettes that disappear, workspaces that can't be applied, and things like the layers palette losing its little boxes so that I can't move things between layers. trashing and restoring preferences of course fixes these, most times, but they all return after a fairly short time. Restoring preferences often causes the CC syncing preferences to disappear so that every time you make a new colour for example it gets synced to the Creative Cloud because there is no way to tell it not to. CS6 NEVER crashes or exhibits irritating behaviour anything like this. I don't use CC2017 as in testing we have done it is too slow but also because of the huge number of reports of it's instability. We revisit it occasionally when we have time, but it's still not worth rolling it out to our studio Macs until it settles down.
