I'd vote for not including it. The current table is way out of sync already.
I first chose the timezones for the Default-set based on this table in the
docs but then I noticed that the table does not really reflect the timezones
in the source code. With the view it's now almost trivial to keep both
synced but it still is a source of errors. Furthermore since nobody has
complained about the incorrect table so far, I don't think many people care.
And those who do can easily consult the view or the file of the Default set
directly.
