[tz] Preparing to fork tzdb

Hello all,

Might I point out that there is another option available — section 4
of RFC 6557 (Procedures for Maintaining the Time Zone Database) [1]
provides a mechanism for replacing the TZ coordinator in the case that
"The TZ Coordinator is not performing the function in accordance with
community wishes."

I personally am ambivalent about the changes in question, and overall
have very little stake in this, but I would hate to see such drastic
action as a fork taken before all other avenues have been exhausted.
