Yes, it's a question of what's "minor" and so on.

I understand the costs of change.

I also understand the costs of maintaining multiple
versions, and I understand the cost of keeping a design
fixed when it could have been improved.

I have evaulated all that, and I am reasonably confident
that the new timezone design is worthwhile. But I can understand
if you (or anybody else) come to a different conclusion.

Hmm... I don't know. Nothing occurs to me just now, but I can imagine
that somebody might come up with a design that does that.
