Honestly, the primary reason I support this is to get developers out of the habbit of demanding a localized server timezone. As an infra' person, I want system time in UTC. If developers get in the habbit of setting TZ, then I can have this!

It feels like any code that needs to know the timezone of the server is inherently wrong. If timezone ever comes up in any context, it's either the timezone of the client from whom the request originates - in which case it should come as part of the request - or else the timezone somehow associated with the business process (e.g. "warehouse open 8-5 Eastern time"), in which case it should be part of the configuration for that one service.
