That's a good start, thank you.
I think it's places like this where a warning to policy makers should
be. Lawmakers and their assistants are more likely to find it. I think
an explanation page should reside in the main TzDb page.
I think Kin Davie's paragraph is a good start for a more complete
explanation.
Because of this propagation time, it is crucial that policymakers
provide a year or more advance notice to IANA before changes to their
time zone policies take effect. Without this lead time it is almost
guaranteed there will be great confusion caused by the use of
inconsistently distributed time zone data.
