Your support org can already do that via a cron job (or equivalent) that 
retrieves the current version from the development repository. Something 
like the following shell script:

   { test -d tz || git clone https://github.com/eggert/tz; } &&
   cd tz &&
   git pull &&
   make version &&
   cat version

This grabs the latest development source code and data, and outputs its 
version number. I just now ran the script, and its output was 
"2016j-38-g46c2bbf", the current development version number.

Your support org can run a script like this on the 15th of every month, 
or every day if they like. Or they can run it only intermittently, when 
they see a change that is urgent for them even if it's not considered 
urgent in general. The ICU folks can do this too, if they want.

An advantage to doing it this way, is that a support organization can 
choose a schedule that's right for it. This is better than the tz 
project imposing the same schedule on every downstream user, as no 
single schedule will be right for everybody.
