Hi, guys

In https://github.com/python/cpython/pull/4904, I made csv.DictReader
returning regular dict instead of OrderedDict. But this code could break
existing code that relied on methods like move_to_end() which are present
in OrderedDict() but not in dict().

As rhettinger suggested, such code is either unlikely or rare, so it would
be net less disruptive for users to just go forward with this patch.

So, would we just go forward with this patch or having a deprecation period
before this patch?

Any help is big thanks.
