Having Etc/UTC+14 mean the opposite of Etc/GMT-14 would probably cause
more confusion than it would cure.  Even your patch was confused to
some extent, since, for example:

> Zone	Etc/UTC-14	-14	-	UTC-14	# 14 hours ahead of UTC

has a comment that is wrong, and the Zone line posits a time zone 14
hours behind UTC, which is something that has no practical use nowadays.

I'd be more inclined to move the confusing Etc/... entries to "backwards".
(After all, they are backwards from the normal convention.  :-)
