The impression that I get is that the SQL Standard has become more
descriptive and less prescriptive. It takes things that exist and
builds the standard around those, so by implementing this draft feature, we
help ensure that it makes it into the standard.
This might be counter-intuitive, but that's what dictionaries do: they
describe how the language is used (descriptive), rather than dictate how it
should be used (prescriptive).
