It is superfluous now, but if the PRC ever reinstitutes DST it will
almost certainly apply to Asia/Macau as well, so I suspect it's
somewhat more likely to be less work in the future if we just leave
things be now.

I suspect Hong Kong would be similar as far as DST, but I've held off
on touching Hong Kong since my vague impression is that "HKT" is still
more popular than "CST" as an English-language abbreviation for the
time in Hong Kong.
