And I think any OS that can release updates for printer drivers, camera RAW input processing modules, and Web browsers without bundling them into a complete OS release can also release updates for the timezone databases without bundling them into a complete OS release.  (For the phones, tablets, set-top boxes, watches, etc., you could probably just push the update without even showing it to the user; localtime() etc. use notify(3) so that you shouldn't even need to reboot.)

Perhaps other OSes using the tzdb should figure out how to do individual component updates and apply that to the tzdb.

Exactly.
