> I'm curious on why you think its possible not to expose TZ. I didn't meant that. I'm dissecting the problem into two cases here: for end users it is always possible to replace the tzid with labels (possibly tailored) so tzid doesn't have to be exposed at all, and for developers it is required to abolish textual tzids. The latter would require the cooperation and concensus from tzdb's (and contributors') part.
