Do you mean territories switch to another timezone 100+ times a year, or
that the details of the timezone (DST dates etc) change 100+ times a
year? If it's the latter, it won't be a problem for OSM if we only store
the TZ name. Looking at the archives of the tz-announce mailing list,
there are only 1-2 actual changes per month which would affect OSM. I
think there are more changes to admin boundaries than to timezones.
In what way would the tzdata maintainers need to be "on board"?
