Assuming this gets included in 3.5 (which will be released around the
end of 2015), are they planning to disregard all the previous 3.x
releases and then wait a couple more years (so 2018+) for 3.5 to
become common?
Are they going to support 3.3+ only (with u'...') and have extra cruft
for 3.3/3.4 to deal with the missing iter* methods and then remove the
cruft once 3.5 is the oldest 3.x release that is supported?
What happens if this addition will still not push people to move their
code to 3.x and similar requests are made for 3.6+ (and shift what I
just said for another 18 months)?
