I do not understand why we persist in pretending this is true when we know it 
is not!

I wrote "users unfamiliar with the naming scheme" not "end users". An application does these users a real disservice if it merely shows labels without any further advice or documentation. Such an application cannot be expected to work well.


It is kind of offensive, also, to James, given that he wrote:

Are we really telling James that he is supposed to go change Google Calendar. 
AND Zoom?

He shouldn't need to. I just now tried both applications, and neither showed me "Indian/Mauritius" among my selections. Google Calendar's menu had an entry "(GMT+04:00) Mauritius Standard Time". Zoom's menu didn't list Mauritius so I suppose users are expected to select its "(GMT+4:00) Dubai" or "(GMT+4:00) Muscat" or "(GMT+4:00) Baku, Tbilisi, Yerevan" entries - not the best UI but it's not TZDB's problem. Although there may be other parts of those applications where users can enter raw TZDB labels, it's still good advice to do that sort of thing only if you know what you're doing.

I agree that too many systems ask naive users to use TZDB labels. However, this doesn't mean we should get into the business of maintaining lots (and there will be lots) of aliases to minimize pain for these naive users. That's beyond our capacity and expertise, and CLDR is a better home for that sort of thing.


some people use tzselect but other people still have to manipulate symbolic 
links to /etc/localtime

The vast majority of users do neither. They use a graphical interface that uses either a map or localized names. Yes, expert users need to know TZDB labels, but they don't need further aliases to do their jobs.
