Hi @tonywhitelive,
Thanks for testing the list & thanks for pushing for continuous improvements and better documentation. Based on what you said, I tested and crossed from the list both default login (matching the file option you pointed to) and Keychain Access. I did not test anything else.
Sorry for not testing things much further. As you know, this is really the type of things Claris should document better.
This only proves how hard it is to make sense of what can and cannot be changed on a hosted file.
Also, please note that I do not see what is here as actual documentation, nor am I trying to claim so (the text "Here is what I can come up with, without putting too much effort into this." says it all). I see it more like a wiki (even attempting to credit contributors as much as possible): to update as knowledge increases & to correct when proven wrong, pretty much the way stuff works with any hypothesis in science in general. Looking at the questions I had towards the end of the post, it seems like I did not have access to much that would let me test things out when I first wrote the list. It is also like the rest of the free stuff out there: rely on it at your own risk, expect no warranties or support of any kind.
I do not think I can do much by myself. Our strength is in numbers: power to community contributions!
Widening the discussion, I hope no ones feel like putting forward a list or anything else necessarily comes with the burden of providing "official documentation" level of accuracy. I think that would only deter people from making contributions and I think the community would lose in the process. Even official documentation is not always as accurate as we would hope.
"Thank you for making a list and checking it twice": You are welcome for the first item. If the second item was expected, I'll attempt being bolder in my disclaimers the next time around, but I would recommend adjusting expectations.
"Upgrading anything below FM16" is a strange comment coming from the guy who asked about this recently.
See you around at a virtual meetup sometime soon, or the NY one - I hear you guys will bring out the big guns on your soon-to-be-any-moment-now virtual gathering.
