On any RedHat-ish system, one can get the TZ version very easily by doing:

*** snip snip ***
[fredg at elastigirl ~]$ rpm -q tzdata
tzdata-2018e-3.el7.noarch
*** snip snip ***

Or the equivalent programmatic call to the RPM database.

This, of course, is horrendously platform-specific, but that illustrates the larger point: TZDB has historically been integrated in all sorts of ways on all sorts of platforms; to expect a new ‘one true way to get the version’ to get any kind of traction at this point is rather utopian.

Cheers!
